Here's a Java program that should do what you're asking for:
java
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
// Get size of matrix from user
System.out.print("Enter the number of rows: ");
int n = sc.nextInt();
System.out.print("Enter the number of columns: ");
int m = sc.nextInt();
// Create matrix and populate with values from user
int[][] matrix = new int[n][m];
for (int i = 0; i < n; i++) {
for (int j = 0; j < m; j++) {
System.out.print("Enter value for row " + (i+1) + " column " + (j+1) + ": ");
matrix[i][j] = sc.nextInt();
}
}
// Check if each row is sorted in descending order
boolean isDescending = true;
for (int i = 0; i < n; i++) {
for (int j = 0; j < m-1; j++) {
if (matrix[i][j] < matrix[i][j+1]) {
isDescending = false;
break;
}
}
if (!isDescending) {
break;
}
}
// Display appropriate message whether rows are sorted in descending order or not
if (isDescending) {
System.out.println("All rows are sorted in descending order.");
} else {
System.out.println("Not all rows are sorted in descending order.");
}
}
}
Here's how this program works:
The program prompts the user to enter the number of rows and columns of the matrix.
It then creates a two-dimensional array named matrix with the specified number of rows and columns.
The user is then prompted to enter a value for each element in the matrix, and these values are stored in the matrix.
The program checks if each row of the matrix is sorted in descending order by comparing each pair of adjacent elements in each row. If an element is greater than its neighbor, the isDescending variable is set to false.
Finally, the appropriate message is displayed based on whether all rows are sorted in descending order or not.
I hope this helps! Let me know if you have any questions.

How the inheritance works in a world of contexts? For example, in space-craft, on earth, and when context changes from one to other?
THIS question is from a course- introduction to artificial intelligence. please answer based on that subject.
In the context of artificial intelligence, inheritance refers to the mechanism by which a class can inherit properties and behaviors from another class. Inheritance allows for code reuse, modularity, and the creation of hierarchies of classes with shared characteristics.
When considering the concept of inheritance in the context of different worlds or contexts, such as a space-craft and on Earth, it is important to understand that inheritance is primarily a programming concept that allows for code organization and reuse. The actual behavior and characteristics of objects in different contexts would be implemented and determined by the specific logic and rules of the AI system.
In the case of a space-craft and Earth, for example, there might be a base class called "Vehicle" that defines common properties and behaviors shared by both space-craft and Earth vehicles. This could include attributes like speed, capacity, and methods for propulsion. Specific subclasses like "Spacecraft" and "EarthVehicle" could then inherit from the "Vehicle" class and define additional attributes and behaviors that are specific to their respective contexts.

6. Give the below tree structure, write a program to add
arbitrary number of nodes to a tree structure.
Language : Java
Program : preferrably blue j
The provided Java program using BlueJ allows you to add an arbitrary number of nodes to a tree structure. It utilizes the TreeNode class to represent nodes and provides methods for adding children and accessing the tree's structure.
Here's an example Java program using BlueJ that allows you to add an arbitrary number of nodes to a tree structure:
import java.util.ArrayList;
import java.util.List;
public class TreeNode {
private int data;
private List<TreeNode> children;
public TreeNode(int data) {
this.data = data;
this.children = new ArrayList<>();
}
public void addChild(TreeNode child) {
children.add(child);
}
public List<TreeNode> getChildren() {
return children;
}
public static void main(String[] args) {
TreeNode root = new TreeNode(1);
// Add child nodes
TreeNode child1 = new TreeNode(2);
TreeNode child2 = new TreeNode(3);
TreeNode child3 = new TreeNode(4);
root.addChild(child1);
root.addChild(child2);
root.addChild(child3);
// Add more nodes
TreeNode grandchild1 = new TreeNode(5);
TreeNode grandchild2 = new TreeNode(6);
child1.addChild(grandchild1);
child1.addChild(grandchild2);
// Add more nodes...
// Access the tree structure
List<TreeNode> rootChildren = root.getChildren();
// ...
// Perform operations on the tree as needed
}
}
In this program, the `TreeNode` class represents a node in the tree. Each node can have an arbitrary number of child nodes, stored in the `children` list. The `addChild` method allows you to add a child node to a parent node, and the `getChildren` method returns a list of child nodes for a given node.
You can add more nodes by creating new instances of `TreeNode` and using the `addChild` method to add them to the appropriate parent nodes.
Please note that this is a basic implementation, and you can modify it as per your specific requirements.

1. Explain the 4 phases of the TLS handshake protocol in detail. Give an example of recently known attack on TLS. (30 Points)
The TLS handshake protocol consists of four phases: Client Hello, Server Hello, Key Exchange and Authentication, and Establishing Secure Connection.
An example of a recent attack on TLS is the "DROWN" attack, which exploits vulnerabilities in SSLv2 to decrypt TLS traffic.J
The Transport Layer Security (TLS) handshake protocol is responsible for establishing a secure connection between a client and a server. It consists of four phases:
1. **Client Hello**: The client initiates the handshake by sending a Client Hello message to the server. This message includes the TLS version supported by the client, a random number (Client Random), a list of supported cipher suites, and other optional extensions. The server receives this message and moves to the next phase.
2. **Server Hello**: The server responds with a Server Hello message, selecting the highest TLS version that is supported by both the client and the server. The server generates a random number (Server Random), selects a cipher suite from the client's list of supported suites, and sends this information to the client. The server may also include its digital certificate for authentication purposes.
3. **Key Exchange and Authentication**: This phase involves the server authenticating itself to the client and exchanging cryptographic keys. The server's digital certificate is used to verify its identity. The client verifies the certificate's validity and checks if it trusts the certificate authority (CA) that issued the certificate. If successful, the client generates a pre-master secret and encrypts it using the server's public key. This pre-master secret is then used to derive the session key.
4. **Establishing Secure Connection**: In this final phase, both the client and server use the pre-master secret and the random values exchanged earlier to independently compute the session key. They then exchange messages to confirm that they have correctly derived the same session key. Once the session key is confirmed, they switch to encrypted communication using symmetric encryption algorithms. The handshake is complete, and secure communication can begin.
**Example of an attack on TLS:**
One recent known attack on TLS is the "DROWN" (Decrypting RSA with Obsolete and Weakened eNcryption) attack. DROWN exploits a vulnerability in the SSLv2 protocol, which is obsolete and considered insecure. The attack targets servers that support SSLv2 and have the same RSA key pair for both SSLv2 and modern TLS versions.
The attack proceeds as follows:
1. The attacker captures the SSLv2 handshake between the client and the server.
2. The attacker initiates a large number of SSLv2 connections and obtains encrypted data.
3. The attacker then performs a series of decryption operations, leveraging a vulnerability in SSLv2 to recover the RSA private key used by the server.
4. With the private key in hand, the attacker can decrypt any intercepted TLS traffic that used the same RSA key pair.
This attack highlights the importance of disabling insecure protocols like SSLv2 and regularly updating TLS configurations to mitigate potential vulnerabilities.

Explain the Diffie-Hellman procedure, using KDC, and how
it establishes a session key between two
parties.
The Diffie-Hellman procedure is a key-exchange technique that allows two parties to establish a shared secret key over an insecure network. In this technique, a third party, known as the Key Distribution Center (KDC), is used to facilitate the process. The KDC generates a shared secret key between the two parties that they can use for encryption and decryption.
The Diffie-Hellman procedure is a cryptographic technique that enables two parties to establish a shared secret key over an insecure network. The following steps describe the Diffie-Hellman procedure using the KDC to establish a session key between two parties:
The KDC generates a large prime number (p) and a generator (g), where p and (p-1)/2 are both prime numbers. The values of p and g are then shared with the two parties.The two parties (Alice and Bob) agree on a random private key, which is kept secret.Alice calculates A = g^(a) mod p and sends A to the KDC. Bob calculates B = g^(b) mod p and sends B to the KDC.The KDC calculates the shared secret key K = B^(a) mod p = A^(b) mod p and sends K to Alice and Bob.Alice and Bob both calculate the shared secret key using the value received from the KDC. Alice calculates K = B^(a) mod p and Bob calculates K = A^(b) mod p. Both parties end up with the same value of K, which can be used for encryption and decryption.In conclusion, the Diffie-Hellman procedure is a key-exchange technique that allows two parties to establish a shared secret key over an insecure network. The KDC generates a shared secret key between the two parties that they can use for encryption and decryption.

Question 8. Calculate the floating point format representation (single precision) of -14.25.
The single precision floating point representation of -14.25 is: 1 10000010 11010000000000000000000
To calculate the single precision floating point representation of -14.25, we need to consider three components: sign, exponent, and significand.
Sign: Since -14.25 is negative, the sign bit is set to 1.
Exponent: The exponent is determined by shifting the binary representation of the absolute value of the number until the most significant bit becomes 1. For -14.25, the absolute value is 14.25, which can be represented as 1110.01 in binary. Shifting it to the right gives 1.11001. The exponent is then the number of shifts performed, which is 4. Adding the bias of 127 (for single precision), the exponent becomes 131 in binary, which is 10000011.
Significand: The significand is obtained by keeping the remaining bits after shifting the binary representation of the absolute value. For -14.25, the remaining bits are 10000000000000000000000.
Putting it all together, the single precision floating point representation of -14.25 is: 1 10000010 11010000000000000000000. The first bit represents the sign, the next 8 bits represent the exponent, and the remaining 23 bits represent the significand.

Compare and contrast Symmetric Key Cryptography and Public-Key Cryptography.
5.2 Consider the following scenario: Alice and Bob used public-key cryptography technique to send
each other secret messages. What kind of keys did Alice and Bob need to use? How many keys
were needed to be generated for Alice and Bob to send each other secret messages?
Symmetric-key Cryptography and Public-key Cryptography are two types of encryption. Symmetric-key encryption uses only one key for both encryption and decryption. Public-key encryption uses a pair of keys, one for encryption and the other for decryption.
Symmetric Key Cryptography (SKC): Symmetric-key encryption is the oldest and most straightforward encryption method. Both sender and receiver share the same secret key. This key is utilized to encrypt and decrypt the data. Here, the data is encrypted using a secret key, and the same key is used to decrypt the data. This encryption technique provides a high level of confidentiality and speed, but it has a significant disadvantage: how do we distribute the key securely? Because if we distribute the key in public, everyone can access it, and hence the security level will decrease.
Public-Key Cryptography (PKC): Public-key encryption (PKC), also known as asymmetric encryption, uses two keys: one public key and one private key. The public key is used to encrypt the data, and the private key is used to decrypt the data. Here, the data is encrypted using a public key, and the private key is used to decrypt the data. PKC is more secure than SKC because it does not require the distribution of secret keys, and the public key can be exchanged openly between the sender and the receiver. Public key cryptography is slower than symmetric key cryptography, but it has the advantage of being more secure and not requiring secret key distribution. Consider the following scenario: Alice and Bob used the public-key cryptography technique to send each other secret messages. What kind of keys did Alice and Bob need to use? How many keys were needed to be generated for Alice and Bob to send each other secret messages? Alice and Bob will need to use a public key and a private key. They will generate a pair of public and private keys each. So, Alice will use her private key and Bob's public key to encrypt the message. Bob will use his private key and Alice's public key to decrypt the message. Therefore, Alice and Bob will each need to generate a pair of keys, and a total of four keys will be required to exchange secret messages.ConclusionIn this answer, we have compared and contrasted symmetric-key cryptography and public-key cryptography. Symmetric-key encryption uses only one key for both encryption and decryption, while public-key encryption uses a pair of keys, one for encryption and the other for decryption. Public-key cryptography is more secure than symmetric-key cryptography because it does not require the distribution of secret keys.

Equivalent of Finite Automata and Regular Expressions.
Construct an equivalent e-NFA from the following regular expression: (10)* +0
To construct an equivalent ε-NFA (epsilon-Nondeterministic Finite Automaton) from the given regular expression `(10)* + 0`.
we can follow these steps:
Step 1: Convert the regular expression to an NFA
The regular expression `(10)* + 0` consists of two parts connected with the `+` operator:
1. `(10)*`: This part matches any number of occurrences of the string "10".
2. `0`: This part matches the string "0".
To construct the NFA, we'll start by creating separate NFAs for each part and then connect them.
NFA for `(10)*`:
```
Initial state -->-- 1 --(0, ε)-->-- 2 --(1, ε)-->-- 3 --(0, ε)-->-- 2
| |
--(ε, ε)-->-- 4 --
```
NFA for `0`:
```
Initial state --(0, ε)-->-- 5
```
Step 2: Connect the NFAs
We'll connect the NFAs by adding ε-transitions from the final state of the `(10)*` NFA to the initial state of the `0` NFA.
```
Final state of (10)* --(ε, ε)-->-- Initial state of 0
```
Step 3: Add the final state
We'll add a new final state and make all the previous final states non-final.
```
Final state of (10)* --(ε, ε)-->-- Initial state of 0 --(0, ε)-->-- Final state
```
Step 4: Combine all states and transitions
We'll combine all the states and transitions from the previous steps into a single ε-NFA.
```
Initial state -->-- 1 --(0, ε)-->-- 2 --(1, ε)-->-- 3 --(0, ε)-->-- 2

Answer the following the questions below, part a is a sample solution, solve for b and c. (4 points for each for a total of 8 points).
A coin is tossed four times. Each time the result II for heads or T for tails is recorded. An outcome of HHTT means that heads were obtained on the first two tosses and tails on the second two. Assume that heads and tails are equally likely on each toss. a. How many distinct outcomes are possible? b. What is the probability that exactly two heads occur? c. What is the probability that exactly one head occurs?
Distinct outcomes are possible in multiple ways using the multiplication rule. We can find the number of distinct outcomes by multiplying the number of choices available for each toss. In this case, there are two choices, heads or tails.
Therefore, the number of distinct outcomes is:2 × 2 × 2 × 2 = 16. So, there are 16 possible distinct outcomes.b. The probability of getting two heads and two tails can be determined using the binomial probability formula. The formula is given by:P(X = k) = nCk * pk * (1-p)n-kWhere:P(X = k) is the probability of getting k headsn is the number of trialsp is the probability of getting a headk is the number of heads we want to get.In this case, we have n = 4, p = 0.5, and k = 2.
Therefore, P(X = 2) = 4C2 * (0.5)2 * (0.5)2 = 6/16 = 3/8. So, the probability of exactly two heads occurring is 3/8.c. To find the probability of exactly one head occurring, we need to consider all the possible ways that exactly one head can occur. We can get exactly one head in four ways, which are:HTTT, THTT, TTHT, and TTTH. Each of these outcomes has a probability of (1/2)4 = 1/16. Therefore, the probability of getting exactly one head is 4 × (1/16) = 1/4. So, the probability of exactly one head occurring is 1/4.Answer:b. The probability of exactly two heads occurring is 3/8.c. The probability of exactly one head occurring is 1/4.

using Mersenne twister to generate 1000000 bits
To generate 1,000,000 random bits using the Mersenne Twister algorithm, you can utilize a programming language that provides an implementation of the algorithm.
Here's an example using Python's random module, which uses the Mersenne Twister as its underlying random number generator:
import random
def generate_bits(num_bits):
random_bits = ""
# Generate random numbers between 0 and 1 and convert them to bits
for _ in range(num_bits):
random_bits += str(random.randint(0, 1))
return random_bits
# Generate 1,000,000 random bits
bits = generate_bits(1000000)
print(bits)
In this example, the generate_bits function generates random numbers between 0 and 1 and converts them into bits by appending them to the random_bits string. The function returns the resulting string of random bits.
Note that the random module in Python is based on the Mersenne Twister algorithm and provides a good source of random numbers for most purposes. However, if you require cryptographically secure random numbers, it is recommended to use a different library specifically designed for cryptographic applications.

You are given the discrete logarithm problem 2^x ≡6(mod101) Solve the discrete logarithm problem by using (c) brute force
The discrete logarithm problem 2^x ≡ 6 (mod 101) has no solution using brute force.
To solve the discrete logarithm problem 2^x ≡ 6 (mod 101) using brute force, we need to systematically check different values of x until we find the one that satisfies the congruence.
Let's start by evaluating 2^x for various values of x and checking if it is congruent to 6 modulo 101:
For x = 1, 2^1 = 2 ≡ 6 (mod 101) is not satisfied.
For x = 2, 2^2 = 4 ≡ 6 (mod 101) is not satisfied.
For x = 3, 2^3 = 8 ≡ 6 (mod 101) is not satisfied.
...
For x = 15, 2^15 = 32768 ≡ 6 (mod 101) is not satisfied.
Continuing this process, we find that there is no integer value of x for which 2^x ≡ 6 (mod 101) holds.
Therefore, the discrete logarithm problem 2^x ≡ 6 (mod 101) has no solution using brute force.

Hello im currently trying to add two registers in assembly, they give a value that is greater than 256. I wanted to know if someone could provide an example where the result of the addition is put in two registers and then the two registers are used for some other operation, for example: result1 - "01111011" and result2 + "00000101". Any help would be greatly appreciated.
To add two registers in assembly where the result is greater than 256 and store the result in two registers, you can use the carry flag to handle the overflow. Here's an example:
mov al, 0x7B ; value in register AL
add al, 0x05 ; add value to AL
mov result1, al ; store the lower 8 bits in result1
mov ah, 0x01 ; value in register AH
adc ah, 0x00 ; add with carry (using carry flag)
mov result2, ah ; store the upper 8 bits in result2
In this example, result1 will contain the lower 8 bits of the sum, which is "01111011", and result2 will contain the upper 8 bits of the sum, which is "00000101".
In assembly language, when adding two registers that may result in a value greater than 255 (256 in decimal), you need to consider the carry flag. The carry flag is set when there is a carry-out from the most significant bit during addition.
In the given example, the values "01111011" and "00000101" are added using the add instruction. The result is stored in register AL. To handle the carry from the lower 8 bits to the upper 8 bits, the adc (add with carry) instruction is used to add the value in register AH with the carry flag. The carry flag is automatically set by the add instruction if there is a carry-out.
After adding the values, the lower 8 bits are stored in result1 (assuming it is a variable or memory location), and the upper 8 bits are stored in result2. By using the carry flag and splitting the result into two registers, you can effectively handle the overflow and preserve the complete result for further operations if needed.

Load the "mystery" vector in file myvec.RData on Canvas (using load("myvec.RData"). Note that R allows you to store objects in its own machine-independent binary format instead of a text format such as .csv). Decompose the time series data into trend, seasonal, and random components. Specifically, write R code to do the following: Load the data. [show code] Find the frequency of the seasonal component (Hint: use the autocorrelation plot. You must specify the lag.max parameter in acf() as the default is too small.) [show code and plot] Convert to a ts object [show code] Decompose the ts object. Plot the output showing the trend, seasonal, random components. [show code and plot]
A general explanation of the steps you can follow to decompose a time series data into trend, seasonal, and random components using R.
Load the data: You can load the "mystery" vector from the "myvec.RData" file using the load() function in R. Make sure to provide the correct path to the file.
Find the frequency of the seasonal component: To determine the frequency of the seasonal component in the data, you can use the acf() function to compute the autocorrelation and plot the autocorrelation function (ACF) using the plot() function. Specify a large enough lag.max parameter to ensure sufficient lag values are included in the plot.
Convert to a ts object: Once you have loaded the data, you can convert it to a time series object (ts object) using the ts() function. Specify the appropriate frequency based on the seasonal component you identified in the previous step.
Decompose the ts object: Apply the decomposition function decompose() to the ts object, which separates the time series data into trend, seasonal, and random components. You can then access these components using the $ operator, such as decomposed_data$trend, decomposed_data$seasonal, and decomposed_data$random.
Plot the output: Use the plot() function to display the decomposed components, including the trend, seasonal, and random components.

To find: Value of cSolution:
Let's first find f '(x)f(x) = (3x+11) mod 26To find f '(x) we differentiate f(x)w.r.t. x to get:f '(x) = d/dx(3x+11) mod 26= 3 mod 26.
Since 3x = 1 mod 26=> x = (1/3) mod 26
Now f '(x) = 3 mod 26f '(x) = c(x-11) mod 26c(x-11) = 3 mod 26Since GCD(3, 26) = 1
Multiplying both sides by 9 (inverse of 3 in mod 26)9c(x-11) = 9*3 mod 26= 1 mod 26So, c(x-11) = 9 mod 26
Since x = (1/3) mod 26=> x-11 = -10/3 mod 26
Multiplying both sides by 3 to remove fraction=> 3(x-11) = -10 mod 26=> c(-10/3) = 9 mod 26
Multiplying both sides by 3 to remove fraction=> c(-10) = 27 mod 26=> c = 7Correct Option: d. 7

Write a function clean that when is given a string and returns the string with the leading and trailing space characters removed. Details:
you must use while loop(s)
you must not use the strip method
the space characters are the space newline '\n', and tab '\t'
>>> clean (" hello
'hello'
>>> clean (" hello, how are you? כ"י
'hello, how are you?!
>>> clean ("\n\n\t what's up, \n\n doc? >>> clean ("\n\n\t\ what's up, \n\n doc? An \t") \n \t")=="what's up, \n\n doc?"
"what's up, \n\n doc?"
True
The "clean" function takes a string as input and removes the leading and trailing whitespace characters, including spaces, newlines, and tabs.
The "clean" function takes advantage of a while loop to remove leading and trailing spaces. It avoids using the strip method by manually iterating over the string. The function starts by initializing two variables: "start" and "end". The "start" variable is set to 0, representing the index of the first character in the string, while the "end" variable is set to the length of the string minus 1, representing the index of the last character.
The function enters a while loop that continues as long as the "start" index is less than or equal to the "end" index, indicating that there are still characters to process. Inside the loop, the function checks if the character at the "start" index is a whitespace character (space, newline, or tab). If it is, the "start" index is incremented by 1 to move to the next character. The function performs the same check for the character at the "end" index and, if it is a whitespace character, decrements the "end" index by 1 to move to the previous character.
Once the loop finishes, the function constructs a new string by slicing the original string using the updated "start" and "end" indices. The resulting string contains the original string without the leading and trailing whitespace characters. Finally, the function returns this cleaned string as the output.
By utilizing the while loop and careful index manipulation, the "clean" function effectively removes the leading and trailing spaces, newlines, and tabs from a given string without using the strip method.

Section 6: Final Project Part 2 -- Building an AI Player In this section you will implement a sequence of computer players (AI) starting with a simple player working toward a more intelligent player. Each of your functions should return a column number indicating where you want to play the current block. Implement the following functions: play_vertical_matcher (block, board) Given: 'block' which is a number that is a positive power of 2, and 'board' which is a table of integers Return: a column index where the topmost block will match if possible, otherwise return a random column that is not full For game play: given the current block and board, play in a column where the block matches the topmost block (if possible), otherwise play randomly, avoiding full columns.
The `play_vertical_matcher` function is designed to determine the column index where the topmost block matches the given block value. If a matching column is found, its index is returned.
Otherwise, a random non-full column is selected as the output, ensuring valid gameplay.
To implement the `play_vertical_matcher` function, you can follow these steps:
1. Iterate over each column in the `board` from left to right.
2. Check if the topmost block in the column matches the given `block`. If it does, return the column index.
3. If no matching topmost block is found, create a list of columns that are not full.
4. If there are columns that are not full, randomly select one of them and return its index.
5. If all columns are full, you can handle this situation based on your preference. One approach could be to return a special value or raise an exception to indicate that no valid move is possible.
Here's an example implementation of the `play_vertical_matcher` function in Python:
```python
import random
def play_vertical_matcher(block, board):
for col in range(len(board[0])):
if board[0][col] == block:
return col
non_full_columns = [col for col in range(len(board[0])) if board[-1][col] == 0]
if non_full_columns:
return random.choice(non_full_columns)
# Handle the case when all columns are full
# You can raise an exception or return a special value here
# Example usage:
block = 4
board = [
[0, 0, 0, 0],
[0, 0, 0, 0],
[0, 0, 0, 0],
[0, 0, 0, 0],
[2, 0, 0, 0],
[4, 0, 0, 0]
]
column = play_vertical_matcher(block, board)
print("Column to play:", column)
```
In this example, the function checks if any column has a matching topmost block with the given `block` value. If found, it returns the index of that column. Otherwise, it selects a random non-full column to play in.

Q1. Write a function margin_index_power() that takes as input a matrix A and an argument rows, TRUE/FALSE with a default value of TRUE. margin_index_power(A, rows = TRUE) outputs the matrix A with the elements in the ith row of A taken to the ith power. If rows = FALSE, then do the same but with the columns instead of rows of A.
Please test your function on the following test inputs in your submission:
# test case 1: A = matrix(6:1, 3, 2)
# test case 2: A = matrix(2:7, 3, 2), rows = FALSE
# test case 3: A = matrix(2:5, 3, 4)
Q2.
Write a function is_anti_diagonal() that takes as input a matrix A and outputs TRUE if it is anti-diagonal and FALSE otherwise. While you can assume A is a matrix, you cannot assume that it is square.
Q3.
Write a function called set_border_NA() that takes as input a matrix A and outputs A with its borders set to NA. If A has exactly one row or exactly one column, throw an error of your choosing.
1. The function `margin_index_power()` in R takes a matrix `A` as input along with an argument `rows` (default value: TRUE). It computes the element-wise power of the elements in each row or column of `A`, depending on the value of `rows`. If `rows = TRUE`, it raises each element in the ith row to the power of i. If `rows = FALSE`, it performs the same operation on the columns of `A`. The function returns the modified matrix `A`.
2. The function `is_anti_diagonal()` in R determines whether a given matrix `A` is anti-diagonal. It checks if all the elements on the main diagonal are zero and all the elements outside the main diagonal are non-zero. The function returns TRUE if `A` is anti-diagonal and FALSE otherwise. It handles non-square matrices as well.
3. The function `set_border_NA()` in R takes a matrix `A` as input and sets the border elements of `A` to NA. It first checks if `A` has exactly one row or one column. If so, it throws an error. Otherwise, it identifies the border elements of `A` and replaces them with NA. The modified matrix `A` is then returned as the output.
1. Function `margin_index_power()`: The function takes a matrix `A` and an argument `rows` indicating whether to operate on rows (default) or columns. It uses the `apply()` function to iterate over the rows or columns of `A`. Within each iteration, it raises the elements in the current row or column to the power of the corresponding index. The modified matrix `A` is returned.
2. Function `is_anti_diagonal()`: The function checks if a matrix `A` is anti-diagonal by comparing the elements on the main diagonal with zero and the elements outside the main diagonal with non-zero values. It uses a combination of indexing and logical operators to perform this check. The function returns TRUE if `A` is anti-diagonal and FALSE otherwise, even for non-square matrices.
3. Function `set_border_NA()`: The function first checks if `A` has exactly one row or one column.
