Saved The order of inserting into a binary search tree (average case) is O(1) O(logN) O(N) O(NlogN)
The average case time complexity for inserting elements into a binary search tree (BST) is O(logN), where N represents the number of elements already present in the BST.
In a balanced BST, where the height is logarithmic in relation to the number of elements, the average case for inserting an element is O(logN). This is because the BST maintains a sorted order, allowing for efficient insertion by comparing the values and traversing the tree based on the comparison result. Each comparison reduces the search space by half, resulting in logarithmic time complexity.
However, in the worst case scenario where the BST becomes skewed, such as when inserting already sorted elements, the average case can degrade to O(N), making it equivalent to inserting elements into an unsorted array. This occurs when the BST loses its balanced structure and essentially becomes a linear linked list.
Therefore, the correct answer is O(logN) for the average case order of inserting elements into a binary search tree.

Draft an interactive zero-knowledge proof allowing to prove that you know what the secret message is without uncovering anything about your knowledge and without revealing what the message is.
The prover employs a randomly chosen binary string R to generate a commitment value C' depending on the challenge value x while the commitment value C conceals the secret message M.
Without knowing anything specific about it, the verifier can confirm the prover's commitment and the information that has been made public to decide whether the prover actually knows the hidden message.
In your case, you want to prove that you know the secret message without uncovering anything about your knowledge or revealing the message itself. Here's a draft of an interactive ZKP to achieve this:
Setup:
Choose a secret message, let's call it M.
Generate a commitment value C using a commitment scheme (e.g., Pedersen commitment) that hides the secret message.
Protocol:
Prover (you):
Randomly select a binary string, let's call it R, of the same length as the secret message M.
Calculate a commitment value, C' using the commitment scheme with R.
Send C' to the verifier.
Verifier:
Randomly select a challenge value, let's call it x (e.g., 0 or 1).
Send x to the prover.
Prover:
If x = 0:
Reveal the secret message M to the verifier.
If x = 1:
Reveal the binary string R to the verifier.
Verifier:
Verify the revealed information:
If x = 0, check if the revealed message matches M.
If x = 1, check if the revealed binary string matches R.
Verify the commitment by checking if C' matches the commitment calculated based on the revealed information.
Completion:
Repeat the protocol multiple times to ensure soundness and prevent lucky guesses.
If the prover successfully convinces the verifier in multiple rounds without revealing any information about the secret message M, the proof is considered valid.
In this interactive ZKP, the commitment value C hides the secret message M, and the prover uses a randomly selected binary string R to create a commitment value C' based on the challenge value x. The verifier can verify the commitment and the revealed information to determine if the prover indeed possesses knowledge of the secret message without learning anything specific about it.
Note that this is a simplified draft, and in practice, you would need to use appropriate cryptographic primitives, such as commitment schemes and challenge-response mechanisms, to ensure the security and integrity of the proof.

Choose between bubble sort, selection sort, insertion sort, shell sort, merge sort, and quick sort. (2) If the sorting algorithm contains multiple loops, the array is shown after a few of passes of the outermost loop has completed. (3) If the shorting algorithm is shell sort, Shell's increments are used for the gap i.e. the gap gets reduced by dividing by 2 each pass starting by dividing by the length of the array by 2). (4) If the sorting algorithm is merge sort, the array is shown after the recursive calls have completed on each sub-part of the array. (5) If the sorting algorithm is quick sort, the algorithm chooses the first element as its pivot. For quick sort, the array is shown before the recursive calls are made. a.

e. [-9, -4, 2, 5, 14, 33, 22, 39, 34, 32] Sorting Algorithm: Merge Sort
To determine the sorting algorithms for each view, we can analyze the characteristics of the arrays given.
a. The array [2, 5, 32, 33, 14, -4, 22, 39, 34, -9] is already partially sorted, with smaller elements gradually moving towards the beginning. This is a characteristic of Insertion Sort, where each element is compared and inserted into its correct position within the already sorted portion.
b. The array [2, 5, -4, 14, 22, 32, -9, 33, 34, 39] shows elements being sorted in a pattern based on Shell's increments, which is a characteristic of Shell Sort. Shell Sort divides the array into smaller subarrays and sorts them independently using different gaps.
c. The array [-9, 22, 5, 2, 14, -4, 32, 39, 34, 33] has elements moving towards their correct positions in each pass, which is a characteristic of Selection Sort. Selection Sort selects the smallest element and places it at the beginning of the unsorted portion.
d. The array (2.5, 14, 32, 33, -9, -4, 22, 34, 39) shows elements being partitioned around a pivot, which is a characteristic of Quick Sort. Quick Sort selects a pivot and partitions the array into two subarrays, recursively sorting them.
e. The array [-9, -4, 2, 5, 14, 33, 22, 39, 34, 32] has adjacent elements being merged together in a sorted order, which is a characteristic of Merge Sort. Merge Sort divides the array into smaller subarrays, sorts them independently, and then merges them back together.

Net pop operations: 15 - number of pop operations that raised Empty error message
Since some pop operations raised Empty error and were ignored, the actual number of successful pop operations can be calculated as (15 - number of pop operations that raised Empty error).
Net effect: Net push operations - Net pop operations

One type of analytic evaluation of algorithms is deterministic modeling. Use deterministic modeling and the system workload given to test the below listed scheduling algorithm(s) in terms of the performance criteria, WAITING TIME. Give the waiting time for each individual job AND the average for all jobs. Show your Gantt chart(s). Job Burst Time Arrival Time 1 8 0 2 42 5 3 14 18 11 14 1) Shortest Job First (SJF) 2) Shortest Remaining Job First (SRJF) (preemptive SJF)
To evaluate the performance of the Shortest Job First (SJF) and Shortest Remaining Job First (SRJF) scheduling algorithms in terms of the waiting time, deterministic modeling can be used. The given system workload consists of four jobs with their respective burst times and arrival times. By applying the SJF and SRJF algorithms, the waiting time for each individual job can be determined, along with the average waiting time for all jobs. Gantt charts can also be created to visualize the scheduling of the jobs.
To evaluate the performance of the SJF and SRJF scheduling algorithms, we consider the given system workload with four jobs. The SJF algorithm schedules the jobs based on their burst times, executing the shortest job first. The SRJF algorithm is a preemptive version of SJF, where the job with the shortest remaining burst time is given priority.
By applying these algorithms to the workload, we calculate the waiting time for each individual job, which is the time a job spends in the ready queue before it starts execution. Additionally, we compute the average waiting time for all jobs by summing up the waiting times and dividing by the number of jobs.
To visualize the scheduling, Gantt charts can be created. A Gantt chart represents the timeline of job execution, showing when each job starts and ends.
By employing deterministic modeling and applying the SJF and SRJF algorithms to the given workload, we can determine the waiting time for each job, calculate the average waiting time, and create Gantt charts to visualize the scheduling of the jobs.

It is beneficial to use an adjacency matrix over an adjacency list : when the graph is sparsely connected or when the graph represents a large city with each vertex as an intersection and each edge connecting intersections.
On the other hand, an adjacency list is preferred when |VI + |E| cannot fit in memory or when |El approaches its maximum value |V|^2.
When the graph is sparsely connected, meaning it has relatively few edges compared to the number of vertices, an adjacency matrix can be more efficient. In this case, the matrix would have many entries with a value of 0, indicating the absence of an edge. Storing these 0 values in the matrix is more space-efficient than maintaining a list of empty adjacency entries for each vertex in an adjacency list.
When the graph represents a large city with each vertex as an intersection and each edge connecting intersections, an adjacency matrix can be advantageous. This scenario typically involves a dense graph with a high number of edges. Using an adjacency matrix allows for constant-time access to determine the existence of an edge between any two intersections.
On the other hand, an adjacency list is preferred when the total number of vertices and edges, denoted as |VI + |E|, cannot fit in memory. An adjacency matrix requires |V|^2 memory space, which can become impractical for large graphs. In such cases, an adjacency list, which only requires memory proportional to the number of edges, is a more efficient choice.
Additionally, when |El approaches its maximum value |V|^2, meaning the graph is nearly complete, an adjacency list becomes more efficient. In a complete graph, most entries in the adjacency matrix would be non-zero, resulting in significant memory wastage. An adjacency list, on the other hand, only stores the existing edges, optimizing memory usage.

Adapter Pattern Adapter pattern works as a bridge between two incompatible interfaces. This type of design pattern comes under structural pattern as this pattern combines the capability of two independent interfaces This pattern involves a single class which is responsible to join functionalities of independent or incompatible interfaces, A real life example could be a case of card reader which acts as an adapter between memory card and a laptop. You plugins the memory card into card reader and card reader into the laptop so that memory card can be read via laptop We are demonstrating use of Adapter pattern via following example in which an audio player device can play mp3 files only and wants to use an advanced audio player capable of playing vic and mp4 files. Implementation We've an interface Media Player interface and a concrete class Audio Player implementing the Media Player interface. Audio Player can play mp3 format audio files by default We're having another interface Advanced Media Player and concrete classes implementing the Advanced Media Player interface. These classes can play vic and mp4 format files We want to make Audio Player to play other formats as well. To attain this, we've created an adapter class MediaAdapter which implements the Media Player interface and uses Advanced Media Player objects to play the required format. Audio Player uses the adapter class MediaAdapter passing it the desired audio type without knowing the actual class which can play the desired format. AdapterPatternDemo, our demo class will use Audio Player class to play various formats.
The Adapter pattern serves as a bridge between two incompatible interfaces. It is a structural design pattern that combines the capabilities of two independent interfaces. In real-life scenarios, an adapter can be compared to a card reader that acts as an intermediary between a memory card and a laptop.
To demonstrate the use of the Adapter pattern, let's consider an example where an audio player device can only play mp3 files. However, we want the audio player to be capable of playing other formats such as vic and mp4. In this implementation, we have a MediaPlayer interface and a concrete class AudioPlayer that implements this interface to play mp3 files. Additionally, we have an AdvancedMediaPlayer interface and concrete classes that implement this interface to play vic and mp4 files. To enable the AudioPlayer to play other formats, we create an adapter class called MediaAdapter.
This adapter class implements the MediaPlayer interface and utilizes AdvancedMediaPlayer objects to play the desired format. The AudioPlayer class uses the MediaAdapter by passing it the desired audio type without needing to know the actual class capable of playing that format. Finally, in the AdapterPatternDemo class, we use the AudioPlayer to play various formats using the adapter.

print("stack:", stack.stack)
if not stack.is_empty():
print("The top name in the list is:", stack.peek())
else:
print("The stack is empty.")
print("The size of the stack is:", stack.size())
This program defines a Stack class with methods to perform stack operations. The push method appends an item to the stack, the pop method removes and returns the top item from the stack, the peek method returns the top item without removing it, the is_empty method checks if the stack is empty, and the size method returns the number of elements in the stack.
The program starts by taking the user's course code and assignment number as input. It then creates an instance of the Stack class and enters a loop to allow the user to push names onto the stack. Each time a name is pushed, the current stack is displayed.
After the user finishes pushing names, the program enters another loop to demonstrate popping names from the stack. The stack is displayed after each pop operation.
Finally, the program checks if the stack is empty and displays the top name (if it exists) and the size of the stack.

The given function is an implementation of Dijkstra's algorithm for finding the shortest path from a source node to all other nodes in a graph. The run time complexity of this function is O(V^2), where V is the number of vertices in the graph.
In each iteration of the outer loop, the function selects the vertex with the minimum cost that has not been processed yet. This operation takes O(V) time. In the inner loop, the function updates the cost of all the neighbors of the selected vertex, which can take up to O(V) time for each vertex. Thus, the overall run time complexity of the function is O(V^2).
To improve the performance of this algorithm, a priority queue based implementation of Dijkstra's algorithm can be used, which reduces the time complexity to O(E log V), where E is the number of edges in the graph.

Deductive reasoning and inductive reasoning are two different approaches to logical thinking and forming conclusions.It involves drawing specific conclusions based on general principles or premises.
In deductive reasoning, the conclusion is derived from established principles or premises that are considered to be true. For example, if we know that all mammals have hair, and a dog is a mammal, then we can deduce that the dog has hair.
On the other hand, inductive reasoning involves drawing general conclusions based on specific observations or evidence. For instance, after observing multiple dogs with hair, we may induce the general conclusion that all dogs have hair.
Deductive reasoning relies on logical consistency and follows a top-down approach, starting with general principles and reaching specific conclusions. Inductive reasoning, on the other hand, relies on probability and follows a bottom-up approach, starting with specific observations and reaching general conclusions.

1. as a computer engineer, briefly explain any two types of CPU scheduling mechanisms available in modern operating systems
2. Discuss any two scheduling algorithms available in an operating system
1 Two types of CPU scheduling mechanisms available in modern operating systems are:
a) Preemptive Scheduling:
b) Non-preemptive Scheduling
Two scheduling algorithms available in operating systems are:
a) Round Robin Scheduling
b) Priority Scheduling:
a) Preemptive Scheduling: In preemptive scheduling, the operating system interrupts a running process and moves it back into the ready queue in order to allow another process to execute. This is done at regular intervals or when higher priority processes arrive. Preemptive scheduling ensures that no single process can monopolize the CPU for an extended period of time.
b) Non-preemptive Scheduling: In non-preemptive scheduling, a running process must voluntarily release the CPU by either blocking itself or completing its execution before another process can execute. This type of scheduling is also known as cooperative scheduling because each process cooperates by releasing the CPU when it's done with its work.
Two scheduling algorithms available in operating systems are:
a) Round Robin Scheduling: In round-robin scheduling, each process is given a fixed time slice or quantum within which it must complete its execution. If the process completes its execution within the allotted time, it is moved to the end of the ready queue. If the time slice expires and the process is not complete, it is preempted and moved to the end of the ready queue.
b) Priority Scheduling: In priority scheduling, each process is assigned a
priority level based on factors like its importance or resource requirements. The process with the highest priority is given access to the CPU first. If two or more processes have the same priority, they can be scheduled using other algorithms, such as round-robin. This algorithm is useful in situations where some processes are more important than others, such as real-time systems.

From your study of the concepts of wireless communication
system, discuss the necessity of "Regulation" using your own words.
(((the answer should not exceed 200 words )))
Regulation plays a crucial role in wireless communication systems. It is necessary to ensure fair and efficient use of the limited wireless spectrum and to address various challenges and concerns related to wireless communication.
Firstly, regulation helps in managing spectrum allocation. The wireless spectrum is a finite resource, and without regulation, there would be chaos and interference as multiple users try to access the same frequencies simultaneously. Regulations define frequency bands for different services and allocate them to different users, such as cellular operators, satellite providers, and Wi-Fi networks. This ensures that each user has their designated spectrum, minimizing interference and maximizing efficiency.
Secondly, regulation is essential for ensuring fair competition and preventing monopolies. Wireless communication services are typically provided by multiple operators, and regulations help to create a level playing field by setting rules and standards that all operators must follow. This prevents any single entity from gaining excessive control over the market, promoting healthy competition, innovation, and affordable services for consumers.
Moreover, regulation is necessary to protect users' rights and privacy. It establishes guidelines for data protection, encryption, and security measures, ensuring that personal information transmitted over wireless networks remains secure. Regulations also address issues like lawful interception, preventing unauthorized access to private communications and protecting against potential threats.

What is true about polynomial regression (i.e. polynomial fit in linear regression)?:
a. It can never be considered linear
b. Sometimes it is linear
c. Although predictors are not linear, the relationship between parameters or coefficients is linear
The correct option is b. Sometimes it is linear is true about polynomial regression (i.e. polynomial fit in linear regression).
Polynomial regression, also known as polynomial fit in linear regression, involves fitting a polynomial function to the data by using linear regression techniques. While the predictors (input variables) themselves may not be linear, the relationship between the parameters or coefficients in the polynomial equation is linear. In polynomial regression, the polynomial function can be represented as a linear combination of the polynomial terms. For example, a quadratic polynomial regression equation may include terms like x, x^2, and constants. Although the predictors (x, x^2, etc.) are nonlinear, the coefficients of these terms can still be estimated using linear regression methods. So, while the polynomial regression model itself is nonlinear due to the higher-order terms involved, the estimation of the coefficients follows a linear approach. This is why option c is true: "Although predictors are not linear, the relationship between parameters or coefficients is linear."

i) Priority Queue: A priority queue is an abstract data type that stores elements with associated priorities. The elements are retrieved based on their priorities, where elements with higher priorities are dequeued before elements with lower priorities.
ii) Complete Binary Tree: A complete binary tree is a binary tree in which all levels except possibly the last level are completely filled, and all nodes are as left as possible. In other words, all levels of the tree are filled except the last level, which is filled from left to right.
iii) Heap: In the context of data structures, a heap is a specialized tree-based data structure that satisfies the heap property. It is commonly implemented as a complete binary tree. Heaps are used in priority queues and provide efficient access to the element with the highest (or lowest) priority.
iv) Heap Condition: The heap condition, also known as the heap property, is a property that defines the order of elements in a heap. In a max heap, for every node `i`, the value of the parent node is greater than or equal to the values of its children. In a min heap, the value of the parent node is less than or equal to the values of its children.

if a[k] > a[parent]:
swap a[k] and a[parent]
update hPos with the new positions
k = parent
else:
break
// Insert an element into the heap
insert(element):
a.append(element)
index = size of the heap
siftUp(index)
```
In the `siftUp()` method, if `hPos[]` was included in the heap code, it would need to be updated every time a swap occurs during the sift-up process. The updated `hPos[]` would be:
```
hPos[0] = 4
hPos[1] = 5
hPos[2] = 6
hPos[3] = 2
hPos[4] = 1
hPos[5] = 3
hPos[6] = 0
hPos[7] = 7
hPos[8] = 8
hPos[9] = 9
hPos[10] = 10
hPos[11] = 11
hPos[12] = 12
```
The complexity of `siftUp()` is O(log n), where n is the number of elements in the heap.
(d) After inserting a node with key 12 into the given heap,
the updated heap would be:
```
13
/ \
12 8
/ \ / \
6 10 5 1
/ \
9 7
```
(e) To convert the given array `[2, 9, 18, 6, 15, 7, 3, 14]` into a heap, we can start from the last non-leaf node and perform the sift-down operation on each node. The steps would be as follows:
```
Step 1: Starting array: [2, 9, 18, 6, 15, 7, 3, 14]
Step 2: Perform sift-down operation from index 3 (parent of the last element)
2
/ \
9 7
/ \
6 15
/ \
18 3
/
14
Step 3: Perform sift-down operation from index 2 (parent of the last non-leaf node)
2
/ \
9 3
/ \
6 7
/ \
18 15

Step 4: Perform sift-down operation from index 1 (parent of the last non-leaf node)
2
/ \
6 3
/ \
9 7
/ \
18 15
/
14
Step 5: Perform sift-down operation from index 0 (root node)
3
/ \
6 7
/ \
9 15
/ \
18 14
Step 6: Final heap:
3
/ \
6 7
/ \
9 15
/ \
18 14
```
The array is now converted into a heap.

Please help me out on this case: write scenarios in an excel spreadsheet to test the profile photo uploding process on an e-wallet application. Create all the possible scenarios that would thoroughly test that the profile photo function is working correctly for a wide diversity of photos. Should be specific with the instructions that is going to be provided so that another tester would be able to follow your instruction clearly. As you go through the uploading process, you must confirm each time that the image becomes visible on the profile page.
An e-wallet application is a type of mobile payment system that allows users to store and manage electronic cash. Users can upload their profile photos, which is an essential feature for any application. The profile photo must be uploaded successfully and be visible on the profile page. In this case, scenarios should be created in an excel spreadsheet to test the profile photo uploading process on an e-wallet application.
Below are scenarios to test the profile photo uploading process on an e-wallet application:
Scenario 1: Uploading a PNG image fileInstructions:
Click on the upload photo Select a PNG image file with a size less than 2MB.Wait for the image to upload4. Confirm that the image is visible on the profile pageScenario 2: Uploading a JPEG image fileInstructions:

1. How many half adders used to implement a full adder? 2. How many full adders needed to add two 2-bit binary numbers? 3. What is the condition for full adder to function as a half adder?
Two half adders are used to implement a full adder.Three full adders are needed to add two 2-bit binary numbers.The condition for a full adder to function as a half adder is that one input and one carry input are forced to zero.
In digital electronics, a full adder is an electronic circuit that performs addition in binary arithmetic. A full adder can be used to add two binary bits and a carry bit, and it can also be used to add two bits to a carry generated by a previous addition operation.In order to implement a full adder, two half adders can be used.
One half adder is used to calculate the sum bit, while the other half adder is used to calculate the carry bit. As a result, two half adders are used to implement a full adder.Two 2-bit binary numbers can be added together using three full adders. The first full adder adds the least significant bits (LSBs), while the second full adder adds the next least significant bits, and so on, until the final full adder adds the most significant bits (MSBs).
The condition for a full adder to function as a half adder is that one input and one carry input are forced to zero. In other words, when one input is set to zero and the carry input is also set to zero, the full adder functions as a half adder, producing only the sum bit without any carry.
