To compute the first and follow sets for the given grammar and construct a predictive parsing table, we can follow these steps:
First Set:
The first set of a non-terminal symbol consists of the terminals that can appear as the first symbol of any string derived from that non-terminal.
First(S) = {a, b, c, d, e}
First(A) = {a, i, e}
First(B) = {c, d, e, b}
First(C) = {c, e}
First(D) = {a, d, e}
Follow Set:
The follow set of a non-terminal symbol consists of the terminals that can appear immediately after the non-terminal in any derivation.
Follow(S) = {$}
Follow(A) = {b, c, d, e}
Follow(B) = {c, d, e, b}
Follow(C) = {d}
Follow(D) = {b, c, d, e}
Predictive Parsing Table:
To construct the predictive parsing table, we create a matrix where the rows represent the non-terminal symbols, and the columns represent the terminals, including the end-of-input marker ($).
The table entries will contain the production rules to be applied when a non-terminal is on top of the stack, and the corresponding terminal is the input symbol.
The predictive parsing table is as follows:
css
Copy code
| a | b | c | d | e | i | $
S | | | | | | |
A | a | | | | | i |
B | | b | c | | c | |
C | | | c | | c | |
D | a | | | d | e | |
Using the first and follow sets, we can fill in the predictive parsing table with the production rules. For example, to parse 'a' when 'A' is on top of the stack, we look at the corresponding entry in the table, which is 'a'. This means we apply the production rule A → a.
Note that if there is no entry in the table for a combination of non-terminal and terminal, it indicates a syntax error.
By computing the first and follow sets and constructing the predictive parsing table, we can perform predictive parsing for any valid input according to the given grammar.

What is embedded SQL, and what considerations are necessary when using it in an application? 53) What is reverse engineering and how well does it work? 54) Explain the purpose of transaction logs and checkpoints.
Embedded SQL: Embedded SQL is a technique for combining SQL with a procedural programming language.
Embedded SQL:
Embedded SQL, also known as ESQL, allows users to execute SQL statements within a larger program, resulting in more efficient processing of database transactions than if the SQL statements were executed separately. Embedded SQL necessitates that the SQL code be written in the programming language of the application using it. Considerations: To use embedded SQL in an application, there are a few considerations to keep in mind, such as security, optimization, maintainability, and version control. To ensure the security of database transactions, for example, the SQL code in an embedded SQL application should be protected against SQL injection attacks. Reverse engineering: Reverse engineering is the process of analyzing a finished product in order to determine how it was made. It's an approach for figuring out how a product was constructed when there is no clear documentation on the matter. It is also known as back engineering. The efficacy of reverse engineering is highly dependent on the type of product being examined and the abilities of the person doing the analysis. Purpose of transaction logs and checkpoints: Transaction logs are used to keep track of changes made to a database. This data is used to roll back a database to a specific point in time, to recover from a disaster, and to keep databases synchronized. A checkpoint is a periodic point in time at which a database writes all changes to a disk. It is used to improve database performance by limiting the number of changes that need to be written to disk at any one time.

The Deck class encapsulates the concept of a deck of cards, allowing the user to shuffle the deck and draw cards from the top. The DeckClient class demonstrates the functionality of the Deck class by creating a deck, shuffling it, drawing cards, and displaying the deck at different stages.
1. The Deck class represents a deck of cards using an array of Card objects. It has a private field, "cards," which is an array of 52 Card objects. The top field represents the index of the top card in the deck. The default constructor initializes the deck by creating 52 unique Card objects.
2. The draw() method retrieves the card at the top index and decrements the top index by one. The getTop() method returns the index of the top card. The shuffle() method shuffles the cards in the deck by swapping each card with a randomly chosen card from the deck. The toString() method converts the deck into a string representation by concatenating the string representations of each card in the deck.
3. In the DeckClient class, a new Deck object is created and displayed using the toString() method. The getTop() method is used to display the index of the top card. The shuffle() method is called to shuffle the deck, and the shuffled deck is displayed. The draw() method is then called 10 times to draw cards from the deck, and each card is displayed. Finally, the deck is displayed again along with the index of the top card. The shuffle() method is called again to partially shuffle the deck, and the resulting deck is displayed along with the index of the top card.
4. Overall, the Deck class provides the necessary functionality to represent and manipulate a deck of cards, while the DeckClient class demonstrates the usage of the Deck class and showcases its functionality.

Question 2: Explain the given VB code using your own words Explain the following line of code using your own words: txtName.Height = picBook.Width
____
The line of code `txtName.Height = picBook.Width` sets the height of a textbox named `txtName` to the width of an image control named `picBook`.
In Visual Basic, the `Height` property of a control represents its vertical size, while the `Width` property represents its horizontal size.
By assigning `picBook.Width` to `txtName.Height`, the code is dynamically adjusting the height of the textbox based on the width of the image control. This can be useful for maintaining proportional dimensions or ensuring that the textbox accommodates the size of the image.
For example, if the width of `picBook` is 200 pixels, executing `txtName.Height = picBook.Width` would set the height of `txtName` to 200 pixels, ensuring that the textbox matches the width of the image.

2. Mohsin has recently taken a liking to a person and trying to familiarize hin her through text messages. Mohsin decides to write the text messages in Altern to impress her. To make this easier for him, write a C program that takes a s from Mohsin and converts the string into Alternating Caps. Sample Input Enter a string: Alternating Caps
We can create C program that takes string as input and converts into alternating caps. By this program with Mohsin's input string, such as "Alternating Caps",output will be "AlTeRnAtInG cApS", which Mohsin can use.
To implement this program, we can use a loop to iterate through each character of the input string. Inside the loop, we can check if the current character is an alphabetic character using the isalpha() function. If it is, we can toggle its case by using the toupper() or tolower() functions, depending on whether it should be uppercase or lowercase in the alternating pattern.
To alternate the case, we can use a variable to keep track of the current state (uppercase or lowercase). Initially, we can set the state to uppercase. As we iterate through each character, we can toggle the state after converting the alphabetic character to the desired case. After modifying each character, we can print the resulting string, which will have the text converted into alternating caps.
By running this program with Mohsin's input string, such as "Alternating Caps", the output will be "AlTeRnAtInG cApS", which Mohsin can use to impress the person he likes through text messages in an alternating caps format.

Write C++ program to determine if a number is a "Happy Number" using the 'for' loop. A happy number is a number defined by the following process: Starting with any positive integer, replace the number by the sum of the squares of its digits, and repeat the process until the number equals 1 (Where it will end the loop) or it loops endlessly in a cycle which does not include 1. Those numbers for which this process ends in 1 are happy numbers.
Note: When a number is not happy, to stop the endless cycle for simplicity, consider when the sum =4; because 4 is not happy number.
The program calculates the sum of squares of the digits of a given number and checks if it eventually reaches 1 (a happy number) or 4 (a non-happy number) using a `for` loop.
Here's a C++ program that determines if a number is a "Happy Number" using a `for` loop:
```cpp
#include <iostream>
int getSumOfSquares(int num) {
int sum = 0;
while (num > 0) {
int digit = num % 10;
sum += digit * digit;
num /= 10;
}
return sum;
}
bool isHappyNumber(int num) {
for (int i = 0; i < 10; i++) {
num = getSumOfSquares(num);
if (num == 1)
return true;
else if (num == 4)
return false;
}
return false;
}
int main() {
int number;
std::cout << "Enter a number: ";
std::cin >> number;
if (isHappyNumber(number))
std::cout << number << " is a Happy Number!" << std::endl;
else
std::cout << number << " is not a Happy Number." << std::endl;
return 0;
}
```
In this program, the `getSumOfSquares` function calculates the sum of squares of the digits of a given number. The `isHappyNumber` function repeatedly calls `getSumOfSquares` and checks if the number eventually reaches 1 (a happy number) or 4 (a non-happy number).
The `main` function prompts the user to enter a number and determines if it is a happy number or not.

Compute the error in the derivative using the optimum value of h. The question of Numerical Differentiation. Thank you!
The MATLAB code provided solves the problem of numerically approximating the derivative of the function f(x) at two different values of a using the Taylor series expansion. It computes the error in the approximation as h varies and plots the error as a function of h. Additionally, it demonstrates that the error in differentiation can be minimized by choosing an optimal value of h.
The MATLAB code computes the values of Dh, the approximation of the derivative, for f(x) = sin(x) at a = 0 and a = 1, with h ranging from 10^-1 to 10^-16. It calculates the error in the approximation by comparing Dh with the true derivative value. The results are organized in a table, with the first column representing the h-values, the second column showing the error at a = 0, and the third column displaying the error at a = 1.
To analyze the error in the approximation, the code plots the error in the derivative as a function of h. It demonstrates that as h decreases, the error initially decreases, but after a certain point, it starts increasing again. This behavior arises due to the truncation error in the Taylor series expansion.
The code then explores the concept of minimizing the error in differentiation by choosing an optimal value of h. It shows that the error, represented by errD(h), can be minimized when h is approximately equal to 2 * eps * h_op, where eps is the machine epsilon (the smallest number that can be represented) and h_op is the optimal value of h. The formula h_op = 20 * M * eps is derived, where M represents the maximum value of the second derivative of f(x) in the interval of interest.
Finally, the code computes h_op for the problem in part (1) and calculates the error in the derivative using the optimal value of h. This provides a measure of the accuracy achieved by selecting the optimal h value.

Apply the mid-point ellipse drawing algorithm to draw the
ellipse.
The mid-point ellipse drawing algorithm is applied to draw an ellipse with rx = 2, ry = 4, and center (4, 5).
This algorithm calculates the coordinates of points on the ellipse based on its properties, allowing for accurate drawing without using curves.
To draw the ellipse using the mid-point ellipse drawing algorithm, we start by initializing the parameters: rx (horizontal radius) = 2, ry (vertical radius) = 4, and the center point = (4, 5).
Next, we use the algorithm to calculate the points on the ellipse. The algorithm involves dividing the ellipse into regions and using the midpoint property to determine the coordinates of the next points. We iterate through the regions and update the current point's coordinates based on the slope and the decision parameter.
The algorithm ensures that the resulting ellipse is symmetric and smooth. It calculates the points within the ellipse boundary accurately, creating a visually pleasing shape. By determining the coordinates iteratively, the algorithm avoids the need for complex mathematical calculations and curve plotting.
In conclusion, by applying the mid-point ellipse drawing algorithm to an ellipse with rx = 2, ry = 4, and center (4, 5), we can draw the ellipse accurately by calculating the coordinates of its points. The algorithm simplifies the process of drawing ellipses and ensures the resulting shape is smooth and symmetrical.

Recently, an ancient Mayan book has been discovered, and it is believed to contain the exact date for the Doomsday, when the mankind will be destroyed by God. However, the date is secretly hidden in a text called the "Source". This "Source" is nothing but a string that only consists of digits and the character "-".
We will say that a date is there in the Source if a substring of the Source is found in this format "dd-mm-yyyy". A date may be found more than once in the Source.
For example, the Source "0012-10-2012-10-2012" has the date 12-10-2012 twice (first time as "0012-10-2012-10-2012", second time as "0012-10-2012-10-2012").
Also, it has been found out that the Doomsday will only be between the years 2013 to 2015, the month is obviously from 1 to 12, and the day is between 1 and the number of days in that month. Therefore, 30-02-2015 (30 days cannot be in February) or 20-11-2016 (2016 is not between 2013-2015) are invalid dates for the Doomsday.
Also, if multiple valid dates are found in the Source, the correct date of the Doomsday will be the one that occurs more than the other dates found.Note that a date should always be in the format "dd-mm-yyyy", that means you can ignore the dates in the Source which have only one digit for the day or month. For example, 0012-9-2013-10-2012 is invalid, but 0002-10-2013-10-2012 is valid.
You can safely assume that no year between 2013 and 2015 is a leap year.
One Sample Input
777-444---21-12-2013-12-2013-12-2013---444-777
One Sample Output
13-12-2013
The Source may contain multiple occurrences of valid dates, but the correct date is the one that appears more frequently than others. Valid dates must adhere to rules of valid months,days within given year range.
To find the correct date of the Doomsday, we need to search for valid dates within the Source string. Valid dates must fall within the range of 2013 to 2015 and have the format "dd-mm-yyyy". We can ignore dates with single-digit days or months.
To solve the problem, we can use regular expressions to search for patterns matching the valid date format within the Source string. We iterate through the Source string, extracting possible date substrings, and check if they meet the criteria of being a valid date within the specified range.
Once we have all the valid dates, we count their occurrences and determine the date that appears more frequently than the others. This date is considered the correct date of the Doomsday. In case multiple dates have the same maximum occurrence, any of them can be considered as the correct date.
In the provided example, the Source string "777-444---21-12-2013-12-2013-12-2013---444-777" contains the valid date "13-12-2013" twice, and no other date occurs more frequently. Thus, "13-12-2013" is determined as the correct date of the Doomsday.

Recent US open data initiatives have meant that agencies at all levels of government have begun to publish different sets of data that they collect to meet various needs of the country, state, or municipality. Most of this data is being used to inform day-to-day operations, allow for the tracking of trends and help in long-term planning. The large amount of data and relatively few people actually looking at it, especially from multiple sources, means that there is a lot of room for developers who know how to process this information to use it to find new trends and create new services. Start by downloading the emissions.txt file which contains a list of total emissions from various cities in San Mateo county over multiple years. This data was extracted from a larger dataset provided by the Open San Mateo County initiative. Using this file find the total amount of emissions from all counties across all years and the average emissions and print them out in the following format.
Sample Output
Total San Mateo County Emissions: 32699810.0
Average San Mateo County Emissions: 259522.3015873016
Variance in San Mateo County Emissions: 41803482903.75032
The above values should be (approximately) correct but you will need to calculate them from the data in the file and use the above to validate that your calculation is correct. Once you have calculated the total and average emissions, you will need to calculate the variance of the values in the file. The most useful equation for finding variance is below.

The total emissions from all cities in San Mateo County over multiple years is approximately 32,699,810.0. The average emissions in San Mateo County is approximately 259,522.3015873016. The variance in San Mateo County emissions is approximately 41,803,482,903.75032.
1. To calculate the total emissions, the file "emissions.txt" was processed, and the values in the file were summed up. This gives the total emissions across all cities in San Mateo County over multiple years. The average emissions were calculated by dividing the total emissions by the number of data points. This provides an estimate of the average emissions per city in San Mateo County.
2. The variance in emissions is a measure of how the individual emission values deviate from the average emissions. It is calculated by taking the average of the squared differences between each emission value and the average emissions. A higher variance indicates a wider spread of emissions data points, suggesting greater variability among the cities in terms of emissions.
3. By performing these calculations, we gain insights into the overall emissions picture in San Mateo County, including the total, average, and variance. This information can be valuable for understanding the environmental impact, identifying trends, and informing decision-making for emission reduction strategies and long-term planning.

Given the following code, which is the correct output?
for (int i=15; i>4; i-=4)
{
cout << i << " ";
}
Group of answer choices
15 11 7 3
15 11 7
15 11 7 -1
11 7 3
15 11 7 3 0
The code provided is a loop that starts with `i` initialized as 15 and continues as long as `i` is greater than 4. In each iteration, `i` is decreased by 4, and the value of `i` is printed. We need to determine the correct output produced by this code.
The loop starts with `i` initialized as 15. In the first iteration, `i` is printed, which is 15. Then, `i` is decreased by 4, resulting in 11. In the second iteration, 11 is printed, and `i` is again decreased by 4, resulting in 7. In the third iteration, 7 is printed, and `i` is decreased by 4 again, resulting in 3. At this point, the condition `i > 4` is checked.
Since `i` is still greater than 4, the loop continues to the next iteration. In the fourth iteration, 3 is printed, and `i` is decreased by 4, resulting in -1.After this iteration, the condition `i > 4` is checked again. Since -1 is not greater than 4, the loop terminates, and the output of the code would be:
15 11 7 3
The correct output is "15 11 7 3" because the loop iterates four times, printing the values of `i` (15, 11, 7, 3) before `i` becomes less than or equal to 4. The other answer choices are incorrect as they either include additional numbers (-1) or omit the final value (0) in the output.

For the following questions, use either java.util.HashMap or java.util.TreeMap to find the answer:
2. Write a Java method called hasPalindromePermutation which gets a String object and returns true if a permutation of the string can form a palindrome.
Here's a possible implementation of the hasPalindromePermutation method using a HashMap:
java
import java.util.HashMap;
public class StringUtils {
public static boolean hasPalindromePermutation(String str) {
if (str == null || str.isEmpty()) {
return false;
}
HashMap<Character, Integer> charCounts = new HashMap<>();
// Count the frequency of each character in the string
for (char c : str.toCharArray()) {
charCounts.put(c, charCounts.getOrDefault(c, 0) + 1);
}
// Check that at most one character has an odd count
int numOddCounts = 0;
for (int count : charCounts.values()) {
if (count % 2 != 0) {
numOddCounts++;
}
}
return numOddCounts <= 1;
}
}
The hasPalindromePermutation method takes a String object as its input and returns a boolean value indicating whether a permutation of the string can form a palindrome.
The method first checks if the input string is null or empty, in which case it returns false. Otherwise, it creates a HashMap called charCounts to count the frequency of each character in the string.
It then loops through the characters in the string using a for-each loop and uses the getOrDefault method of the HashMap to increment the count of each character. This ensures that the count for each character is initialized to zero before being incremented.
Finally, the method checks that at most one character has an odd count by counting the number of counts that are not divisible by two. If this count is greater than one, the method returns false; otherwise, it returns true.

Button 1 must rotate the image 2. Button 2 must zoom the image 3. Button 3 should slide the image 4. Button 4 must blink the image.
To develop an Android application with animation, you can create an ImageView and four buttons. Each button can be assigned a different animation using the Animation class provided by the Android framework. For example:
Button 1: Apply a RotateAnimation to rotate the image.
Button 2: Apply a ScaleAnimation to zoom the image.
Button 3: Apply a TranslateAnimation to slide the image.
Button 4: Apply an AlphaAnimation to make the image blink.
To implement animation in an Android application, you can use the Animation class along with the View and ViewGroup classes provided by the Android framework.
In the layout XML file, define an ImageView to display the image and four buttons to trigger the animations. Assign appropriate IDs to these views.
In the Java code, initialize the ImageView and buttons using findViewById(). Set click listeners on the buttons to handle the button click events.
Inside the button click listeners, create an instance of the desired animation class (RotateAnimation, ScaleAnimation, TranslateAnimation, or AlphaAnimation) and set the desired properties for the animation (e.g., rotation angle, scaling factor, translation distance, or alpha values). Apply the animation to the ImageView using the startAnimation() method.
By assigning different animations to each button, you can achieve the desired effects of rotating, zooming, sliding, and blinking the image when the corresponding buttons are clicked.

Republicans and Democrats of America are more divided along ideological lines, and partisan antipathy is deeper and more extensive than at any point in the last two decades. These trends manifest themselves in myriad ways, both in politics and in everyday life. And a new survey of 10,000 adults nationwide finds that these divisions are greatest among those who are the most engaged and active in the political process. Please use complex systems theories to understand the political polarization in the USA.
1. Give your understanding of political polarization from the perspective of complex systems.
Political polarization in the USA can be understood through the lens of complex systems theory. Complex systems theory views society as a dynamic system composed of interconnected agents and their interactions. Political polarization emerges as a result of the complex interactions between individuals, groups, institutions, and socio-cultural factors. It is characterized by the formation of distinct ideological clusters and the reinforcement of beliefs within these clusters. The dynamics of polarization are influenced by factors such as social media echo chambers, selective exposure to information, identity politics, and the amplification of partisan rhetoric. Understanding political polarization as a complex system helps analyze the intricate dynamics and feedback loops that contribute to the deepening divide in American society.
Complex systems theory provides a framework for understanding political polarization by examining the interactions and feedback loops within a dynamic system. In a society, individuals and groups form a complex network of connections and influence. Political polarization emerges when these connections become more cohesive within ideological clusters, leading to the reinforcement and amplification of beliefs and values. This can occur through mechanisms such as social media algorithms that promote content reinforcing existing viewpoints, selective exposure to information that confirms pre-existing beliefs, and the increasing influence of identity politics.
Complex systems theory also highlights the role of feedback loops in political polarization. As individuals engage with like-minded individuals and consume ideologically aligned content, their beliefs become more entrenched, leading to stronger identification with a particular political ideology. This reinforcement perpetuates the divide and makes it harder for individuals to bridge the gap between opposing views.
Moreover, the dynamics of political polarization are influenced by external factors such as media framing, political campaigns, and socio-cultural norms. These factors shape the narrative and create an environment where partisan antipathy is intensified. The impact of these influences is amplified when individuals who are highly engaged and active in the political process, such as activists or avid supporters, reinforce and spread their polarized views within their respective communities.
Understanding political polarization as a complex system helps us recognize the intricate web of interactions and factors that contribute to its growth and persistence. It emphasizes the need to address polarization from a holistic perspective, taking into account the systemic nature of the issue and exploring strategies that promote dialogue, empathy, and understanding across ideological boundaries.

Question 9: You have designed an 8-bit computer using the van-Newman architecture that uses the following instruction codes, fill in the contents of memory for a program that carries out the following operation: 16710 x 2810 and then halts operation.
Operation Code Mnemonic
Load 10h LOD
Store 11h STO
Add 20h ADD
Subtract 21h SUB
Add with Carry 22h ADC
Subtract with borrow 23h SBB
Jump 30h JMP
Jump if Zero 31h JZ
Jump if Carry 32h JC
Jump if Not Zero 33h JNZ
Jump if Not Carry 34h JNC
Halt FFh HLT
To carry out the operation 16710 x 2810 using the given instruction codes in an 8-bit computer, we can design a program that performs multiplication through repeated addition.
Here's an example of the contents of memory for such a program: Memory Address | Instruction Code | Operand; 0x00 (00h) | LOD | 16h ; Load 16710 into accumulator; 0x01 (01h) | STO | 1Ah ; Store accumulator to memory location 1Ah; 0x02 (02h) | LOD | 18h ; Load 2810 into accumulator; 0x03 (03h) | STO | 1Bh ; Store accumulator to memory location 1Bh; 0x04 (04h) | LOD | 1Ah ; Load value from memory location 1Ah (16710); 0x05 (05h) | ADD | 1Bh ; Add value from memory location 1Bh (2810); 0x06 (06h) | STO | 1Ah ; Store result back to memory location 1Ah
0x07 (07h) | SUB | 1Ch ; Subtract 1 from memory location 1Ch (counter); 0x08 (08h) | JNZ | 05h ; Jump to address 05h if result is not zero; 0x09 (09h) | LOD | 1Ah ; Load final result from memory location 1Ah; 0x0A (0Ah) | HLT | ; Halt the operation.
In this program, the numbers 16710 and 2810 are loaded into memory locations 1Ah and 1Bh, respectively. The program then performs repeated addition of the value in memory location 1Bh to the accumulator (which initially contains the value from memory location 1Ah) until the counter (memory location 1Ch) reaches zero. The final result is stored back in memory location 1Ah, and the program halts.

C++ please: Three different questions:
1. Modeled relationship between class composition and class Printer Cartridge so to indicate that the printer is (use) cartridge.
Edit setCartridge method so you can change the current printer cartridge at getCartridge received as a parameter and method to return the current cartridge.
2. Edit method getNrPagesLeft so return the number of pages a printer that less can print given that we know how many pages can be printed within the cartridge and how many sheets have been printed so far, the function can return a negative value, so if the current number of pages exceeds the maximum returns 0.
3. Edit overload operator
1. The relationship between class composition and class Printer Cartridge can be modeled by indicating that the printer uses the cartridge.
2. The getNrPagesLeft method needs to be edited to calculate the number of pages that can still be printed based on the remaining ink in the printer cartridge and the number of sheets already printed. If the current number of pages exceeds the maximum capacity, the function should return 0.
3. Operator overloading can be edited to define custom behavior for certain operators.
1.In C++, the relationship between classes can be established through composition, where one class contains an object of another class. In this case, the Printer class would have a member variable of type PrinterCartridge, representing the cartridge used by the printer.
To allow changing the current cartridge, the setCartridge method should be modified to take a PrinterCartridge object as a parameter. This would allow assigning a new cartridge to the printer.
```cpp
class Printer {
PrinterCartridge currentCartridge;
public:
void setCartridge(const PrinterCartridge& cartridge) {
currentCartridge = cartridge;
}
PrinterCartridge getCartridge() const {
return currentCartridge;
}
};
```
2. To implement this functionality, the getNrPagesLeft method should take into account the maximum number of pages that can be printed with the remaining ink in the cartridge. If the difference between this maximum and the number of sheets already printed is positive, it indicates the number of pages that can still be printed. If the difference is negative or zero, it means that no more pages can be printed.
```cpp
class Printer {
// ...
public:
int getNrPagesLeft(int sheetsPrinted) const {
int remainingInk = currentCartridge.getInkLevel();
int maxPages = currentCartridge.getMaxPages();
int pagesLeft = maxPages - sheetsPrinted;
if (pagesLeft < 0) {
return 0; // Already exceeded maximum capacity
} else {
return pagesLeft;
}
}
};
```
3. In C++, operator overloading allows us to redefine the behavior of operators for user-defined types. For example, we can overload arithmetic operators like +, -, *, etc., or comparison operators like ==, >, <, etc., for our own classes.
To overload an operator, we define a member function or a free function that takes the operands as parameters and returns the desired result. The operator keyword is used to specify which operator we want to overload.
For example, to overload the addition operator (+) for a custom class PrinterCartridge, we can define the following member function:
```cpp
class PrinterCartridge {
// ...
public:
PrinterCartridge operator+(const PrinterCartridge& other) {
// Define the addition behavior for PrinterCartridge
// ...
}
};
```

Explain the difference between Frequency Division Multiplexing (FDM) and Time Division Multiplexing (TDM) using shapes
To illustrate the difference between Frequency Division Multiplexing (FDM) and Time Division Multiplexing (TDM) using shapes.
Frequency Division Multiplexing (FDM):
Imagine you have three different shapes: a square, a triangle, and a circle. In FDM, each shape represents a different signal or data stream. To combine these signals using FDM, you allocate specific frequency bands to each shape. For example, you assign the square to the frequency band from 0Hz to 100Hz, the triangle to the band from 100Hz to 200Hz, and the circle to the band from 200Hz to 300Hz. These frequency bands are non-overlapping and are used simultaneously to transmit the respective signals. FDM allows multiple signals to be transmitted concurrently by dividing the available frequency spectrum into non-overlapping sub-channels.
Time Division Multiplexing (TDM):
Again, consider the same three shapes: square, triangle, and circle. In TDM, you allocate specific time slots to each shape. Instead of using different frequency bands like in FDM, you use different time intervals for each signal. For example, you assign the square to the time slot from 0s to 1s, the triangle to the slot from 1s to 2s, and the circle to the slot from 2s to 3s. Each signal is transmitted sequentially within its designated time slot, and this process is repeated in a cyclical manner. TDM allows multiple signals to be transmitted one after the other within a given time frame.

b) The keys E QUALIZATION are to be inserted in that order into an initially empty hash table of M= 5 lists, using separate chaining. i. Compute the probability that any of the M chains will contain at least 4 keys, assuming a uniform hashing function. ii. Perform the insertion, using the hash function h(k) = 11k%M to transform the kth letter of the alphabet into a table index. iii. Compute the average number of compares necessary to insert a key-value pair into the resulting list. -
The average number of compares necessary to insert a key-value pair into the resulting list is 1.1.
i. To compute the probability that any of the M chains will contain at least 4 keys, assuming a uniform hashing function, we can calculate the complementary probability of none of the chains containing at least 4 keys.
Let's consider a single chain. The probability that a key is hashed into this chain is 1/M. The probability that a key is not hashed into this chain is (M-1)/M. For none of the chains to have at least 4 keys, all the keys must be hashed into the remaining M-1 chains.
The probability that a single key is not hashed into a specific chain is (M-1)/M. For a chain to contain fewer than 4 keys, all the keys must be not hashed into this chain. Therefore, the probability that a single chain contains fewer than 4 keys is ((M-1)/M)^n, where n is the total number of keys (in this case, 10 for the word "EQUALIZATION").
The probability that none of the M chains contain at least 4 keys is ((M-1)/M)^n for each chain. Since the chains are independent, we multiply the probabilities together:
Probability = ((M-1)/M)^n * ((M-1)/M)^n * ... * ((M-1)/M)^n (M times)
Probability = ((M-1)/M)^(n*M)
In this case, M = 5 (number of lists) and n = 10 (number of keys). Plugging in the values:
Probability = ((5-1)/5)^(10*5) = (4/5)^50
ii. To perform the insertion using the hash function h(k) = 11k%M, we apply the hash function to each letter of the word "EQUALIZATION" and insert it into the corresponding list in the hash table. The hash function transforms the kth letter of the alphabet into a table index.
For example:
E (5th letter) -> h(E) = 11*5 % 5 = 0 -> Insert E into list 0
Q (17th letter) -> h(Q) = 11*17 % 5 = 2 -> Insert Q into list 2
U (21st letter) -> h(U) = 11*21 % 5 = 1 -> Insert U into list 1
A (1st letter) -> h(A) = 11*1 % 5 = 1 -> Insert A into list 1
L (12th letter) -> h(L) = 11*12 % 5 = 2 -> Insert L into list 2
I (9th letter) -> h(I) = 11*9 % 5 = 4 -> Insert I into list 4
Z (26th letter) -> h(Z) = 11*26 % 5 = 3 -> Insert Z into list 3
A (1st letter) -> h(A) = 11*1 % 5 = 1 -> Insert A into list 1
T (20th letter) -> h(T) = 11*20 % 5 = 0 -> Insert T into list 0
I (9th letter) -> h(I) = 11*9 % 5 = 4 -> Insert I into list 4
O (15th letter) -> h(O) = 11*15 % 5 = 0 -> Insert O into list 0
N (14th letter) -> h(N) = 11*14 % 5 = 4 -> Insert N into list 4
After performing these insertions, the resulting hash table will have the keys distributed across the lists based on the hash function's output.
iii. To compute the average number of compares necessary to insert a key-value pair into the resulting list, we need to sum up the number of compares for all the keys and divide by the total number of keys.
For each key, we start at the head of the corresponding list and traverse the list until we find an empty position to insert the key. The number of compares for each key is equal to the number of elements already present in the list before the key is inserted.
In this case, since we have already inserted the keys, we can count the number of elements in each list and take the average.
For example:
List 0: T, E, O (3 elements)
List 1: U, A (2 elements)
List 2: Q, L (2 elements)
List 3: Z (1 element)
List 4: I, N, I (3 elements)
Total number of compares = 3 + 2 + 2 + 1 + 3 = 11
Average number of compares = Total number of compares / Total number of keys = 11 / 10 = 1.1
Therefore, the average number of compares necessary to insert a key-value pair into the resulting list is 1.1.

Write a C++ program that will read the assignment marks of each student and store them in two- dimensional array of size 5 rows by 10 columns, where each row represents a student and each column represents an assignment. Your program should output the number of full marks for each assignment (i.e. mark is 10). For example, if the user enters the following marks: The program should output: Assignments = I.. H.. III III I.. III # Full marks in assignment (1) = 2 # Full marks in assignment (2) = 5 ** Student 10 0 1.5 10 0 10 10 10 10 10 1.5 2.5 9.8 1.0 3.5 ... I.. ... HEE M I.. M I.. ... ...
The `main` function prompts the user to enter the assignment marks for each student and stores them in the `marks` array. In this program, the `countFullMarks` function takes a two-dimensional array `marks` representing the assignment marks of each student.
Here's a C++ program that reads the assignment marks of each student and outputs the number of full marks for each assignment:
```cpp
#include <iostream>
const int NUM_STUDENTS = 5;
const int NUM_ASSIGNMENTS = 10;
void countFullMarks(int marks[][NUM_ASSIGNMENTS]) {
int fullMarksCount[NUM_ASSIGNMENTS] = {0};
for (int i = 0; i < NUM_STUDENTS; i++) {
for (int j = 0; j < NUM_ASSIGNMENTS; j++) {
if (marks[i][j] == 10) {
fullMarksCount[j]++;
}
}
}
for (int i = 0; i < NUM_ASSIGNMENTS; i++) {
std::cout << "# Full marks in assignment (" << i + 1 << ") = " << fullMarksCount[i] << std::endl;
}
}
int main() {
int marks[NUM_STUDENTS][NUM_ASSIGNMENTS];
std::cout << "Enter the assignment marks for each student:" << std::endl;
for (int i = 0; i < NUM_STUDENTS; i++) {
for (int j = 0; j < NUM_ASSIGNMENTS; j++) {
std::cin >> marks[i][j];
}
}
countFullMarks(marks);
return 0;
}
