The task requires an explanation of circular linked lists in the C programming language.
A circular linked list is a type of linked list where the last node of the list points back to the first node, forming a circle. Unlike a traditional linked list that ends with a NULL pointer, a circular linked list does not have a NULL pointer at the end. Instead, the last node's next pointer is set to the address of the first node.
To implement a circular linked list in C, you would define a structure for each node containing the data and a pointer to the next node. The last node's next pointer would be set to the address of the first node.
When traversing a circular linked list, you start at any node and continue visiting the next nodes until you reach the starting node again. This looping behavior allows for efficient operations such as iterating over the entire list or searching for specific elements.
Circular linked lists are commonly used in situations where you need continuous access to the elements and want to avoid the NULL termination of traditional linked lists.
In C, a circular linked list is a linked list where the last node points back to the first node, forming a circular structure. It is implemented by setting the last node's next pointer to the address of the first node. Circular linked lists provide continuous access to the elements and avoid the need for NULL termination. They are useful in scenarios where circular traversal or continuous data access is required.

"Think left and think right and think low and think high. Oh, the thinks you can think up if only you try!"
Which of these character pairs would the algorithm replace?
Note that there may be multiple answers to this question.
Byte pair encoding is a data compression algorithm that works by replacing repeated character pairs in a string with a character that is not found in the data, and then creates a table of replacement mappings. The character pairs that the algorithm would replace from the given quote are "hi," "th," "nk," "in," "ou," and "an."
Byte pair encoding (BPE) is a lossless data compression algorithm that is used in data compression tasks to replace repeated character pairs in a string with a character that is not found in the data. The algorithm then creates a table of replacement mappings. It is a common compression technique for language processing and NLP. Given the quote from Dr. Seuss, the following character pairs would be replaced by the BPE algorithm:"hi""th""nk""in""ou""an"The byte pair encoding algorithm will first count the frequency of each character in the text. It will then merge the two most common characters and add the new character to the text. This process is repeated until the desired compression level is reached.

1. Define and describe 'data abstraction'. 2. Define and describe 'data encapsulation'. 3. Define and describe ADT. 4. Define and describe namespace.
Data abstraction is a concept in programming that involves representing complex data in a simplified and organized manner, hiding unnecessary details and focusing on essential features.
Data encapsulation, on the other hand, refers to the bundling of data and the methods or functions that manipulate that data into a single unit, known as an object. Abstract Data Types (ADTs) are high-level data structures that provide an interface for accessing and manipulating data, without exposing the implementation details. Finally, a namespace is a container that holds a set of identifiers, such as variables, functions, and classes, to prevent naming conflicts and provide organization within a program.
Data abstraction involves creating simplified representations of complex data, allowing programmers to work with higher-level concepts rather than dealing with low-level details. It helps in managing the complexity of large-scale systems by breaking them down into smaller, more manageable parts. Abstraction allows us to focus on what the data represents and the operations we can perform on it, without worrying about the internal implementation. By hiding irrelevant details, it enhances code readability and maintainability.
Data encapsulation, also known as information hiding, combines data and the methods or functions that operate on that data into a single unit, called an object. Encapsulation provides the benefits of data abstraction while also ensuring data integrity and controlling access to the data. By encapsulating data, we can define access restrictions and enforce certain rules on how the data can be modified. This protects the data from being accessed or modified in unintended ways, promoting better code organization and reducing the risk of errors or inconsistencies.
Abstract Data Types (ADTs) are high-level data structures that define a set of operations without specifying the implementation details. They provide a way to encapsulate data and operations into a single unit, allowing programmers to define their own data types and manipulate them using a well-defined interface. ADTs allow for modularity and code reuse, as they can be used as building blocks for more complex data structures and algorithms. Examples of ADTs include stacks, queues, lists, and trees, which provide common data structures with a defined set of operations.
Namespaces are used to organize and group identifiers in a program, preventing naming conflicts and improving code clarity. They provide a way to avoid clashes between variables, functions, and classes that have the same name but serve different purposes. Namespaces help in avoiding ambiguity by providing a scope in which the names are unique. They allow programmers to categorize and differentiate between different components of a program, making it easier to manage and understand large codebases. Namespaces also facilitate modularity and code organization, as related elements can be grouped together under a specific namespace.

The given m-script file should be modified and proceed to filter the "chirp plus sinusoidal" input signal. This can be done using the bandpass filter designed to filter and retain the "KO" or sinusoidal sound. The signal after filtering can be plotted using the given commands in the m-script file. Below is the modified m-script file: ExplanationIn the given problem, we are provided with an m-script file and we are required to modify the file to filter the "chirp plus sinusoidal" input signal.
This can be done using the bandpass filter designed to filter and retain the "KO" or sinusoidal sound.The given m-script file is:clear allclose allclcfs = 8000;t = 0:1/fs:1;f1 = 100;f2 = 5000;s = chirp(t, f1, 1, f2);sn = s + 0.05 * randn(size(s));a1 = 1;a2 = [1 -0.9];sout1 = filter(a1, a2, sn);a3 = [1 -1.8 0.81];sout2 = filter(a1, a3, sn);sound(sout1, fs);plot(sout1);The modified m-script file is:clear allclose allclcfs = 8000;t = 0:1/fs:1;f1 = 100;f2 = 5000;s1 = chirp(t, f1, 1, f2);s2 = sin(2*pi*1000*t);s = s1 + s2;sn = s + 0.05 * randn(size(s));fcl = 950;fch = 1050;B = fch - fcl;fc = (fch + fcl) / 2;Wn = [B/fs fc/fs];N = 25;h = fir1(N, Wn, 'bandpass');sout1 = filter(h, 1, sn);sound(sout1, fs);plot(sout1);In the modified m-script file, a sine wave with a frequency of 1000 Hz is generated using the sin() function. This is then added to the chirp signal generated using the chirp() function.
The signal is then passed through a bandpass filter designed to filter and retain the "KO" or sinusoidal sound.The bandpass filter is designed using the fir1() function. The bandpass frequency range is set to 950-1050 Hz using the variables fcl and fch. The mid-frequency point fc is calculated as the average of fcl and fch. The bandwidth of the bandpass filter B is calculated as the difference between fch and fcl. The normalized bandpass frequency range Wn is then calculated as [B/fs fc/fs]. The length of the filter N is set to 25. The filter coefficients h are then calculated using the fir1() function with the inputs N, Wn, and 'bandpass'.The chirp plus sinusoidal signal is then passed through the bandpass filter using the filter() function with the inputs h and 1. The filtered signal sout1 is then plotted using the plot() function. Finally, the sound() function is used to play the filtered signal at the sampling frequency fs.

The output of the given code will be: "I'm sure if I study hard, I'll do well! I am getting prepared for the final! I am getting prepared for the final!"
In the given code, the function f is defined, which takes a string s as a parameter. Inside the function, the print statement is used to print the value of s followed by a space, without inserting a new line character.
In the main part of the code, the string s is initially assigned the value "I'm sure if I study hard, I'll do well!" and printed using the print statement with end = ' '. This prints the string followed by a space, keeping the output on the same line.
Then, the value of s is reassigned to "I am getting prepared for the final!" and passed as an argument to the function f. Inside the function, the value of s is printed with a space, again keeping the output on the same line.
Finally, outside the function, the value of s is printed using the print statement without specifying end = ' ', which inserts a new line character after printing the string.

Write a complete C++ modular program. You will need main and 3 additional modules - InData, Calc, and OutData. From main call InData to input three integers from the user in module InData. Call Calc from main to determine the largest and smallest of the numbers. Call module OutData from main to output the floats and the largest and smallest in OutData. Use a prototype for each function before main and then write out each function after main.
The program modules: main, InData, Calc, and OutData. InData inputs three integers, Calc finds the smallest, largest numbers, and OutData outputs values. Modules communicate with the main function through parameters.
#include <iostream>
// Function prototypes
void InData(int& num1, int& num2, int& num3);
void Calc(int num1, int num2, int num3, int& smallest, int& largest);
void OutData(int num1, int num2, int num3, int smallest, int largest);
int main() {
int num1, num2, num3;
int smallest, largest;
// Input data
InData(num1, num2, num3);
// Calculate smallest and largest
Calc(num1, num2, num3, smallest, largest);
// Output data
OutData(num1, num2, num3, smallest, largest);
return 0;
}
// Module to input data
void InData(int& num1, int& num2, int& num3) {
std::cout << "Enter three integers: ";
std::cin >> num1 >> num2 >> num3;
}
// Module to calculate smallest and largest
void Calc(int num1, int num2, int num3, int& smallest, int& largest) {
smallest = std::min({num1, num2, num3});
largest = std::max({num1, num2, num3});

// Module to output data
void OutData(int num1, int num2, int num3, int smallest, int largest) {
std::cout << "Numbers: " << num1 << ", " << num2 << ", " << num3 << std::endl;
std::cout << "Smallest: " << smallest << std::endl;
std::cout << "Largest: " << largest << std::endl;
}
The program consists of four modules: InData, Calc, OutData, and main.
The InData module takes three integer inputs from the user and assigns them to num1, num2, and num3.
The Calc module receives the three input values and calculates the smallest and largest numbers using the std::min and std::max functions.
The OutData module outputs the three input values, as well as the smallest and largest numbers, using std::cout.
Finally, the main function calls these modules in order, passing the necessary parameters.

Static routing is a type of network routing in which the administrator configures routing tables manually instead of using a protocol to automatically update the routing tables. In static routing, the routing table entries are fixed and do not change dynamically in response to network topology changes or network traffic. In other words, static routing is less flexible and more rigid than dynamic routing.
Configuration complexity increases with network size in static routing because every router needs to have its routing table manually configured by the administrator. This means that as the network grows in size, the amount of work required to manually configure all the routers' routing tables increases as well.However, no extra resources such as CPU, bandwidth, or memory are needed in static routing because it does not require any dynamic updates of the routing tables. Once the routing tables are configured, they remain unchanged until the administrator manually updates them.Topology changes will affect configuration in static routing because any change in the network topology requires the administrator to manually update the routing tables of all affected routers. This can be time-consuming and error-prone, especially in large networks with complex topologies.In summary, static routing has the advantage of simplicity and low resource requirements, but it has the disadvantage of being inflexible and requiring manual updates in response to network topology changes. Therefore, static routing is most suitable for small, stable networks with simple topologies.

Problem Two: Constructing NFAs For each of the following languages over the indicated alphabets, use the Automaton Editor to design an NFA that accepts precisely the strings that are in the indicated language. As before, while you don't have to design the smallest NFAs possible, we recommend that you try to keep your NFAs small both to make testing easier and for your own edification. Remember the "guess-and-check" design framework we talked about in class. Also consider if you can use the NFA design pattern of decomposing the language into the union of 2 or more simpler languages that it would be easy to make an NFA/DFA for, and combining them (another tecnique we talked about in class). Some of these will involve a lot of states (in one case, over 50!) and/or transitions if you do them without the special powers of an NFA. Think about what information it would be useful to "guess" in advance, and design around that. i. Let ? = {a, b,c}. Construct an NFA for { w EX* | w ends in a, bb, or ccc}. = = ii. Let S = {a, b, c, d, e}. Construct an NFA for the language L = { w€ I* | the letters in w are sorted alphabetically }. For example, abcde e L, bee E L, a E L and ε E L, but decade L. = iii. Let S = {a, b, c, d, e}. Construct an NFA for the language { w€ 3* | the last character of w appears nowhere else in w, and (w > 1}. iv. Let S = {a,b}. Construct an NFA for the language L {we * | w contains at least two b's with exactly five characters between them }. For example, baaaaab E L, aabaabaaabbb € L, and abbbbbabaaaaaaab E L, but bbbbb & L, bbbab & L, and aaabab & L.
i. Let Σ = {a, b, c}. Construct an NFA for the language { w ∈ Σ* | w ends in a, bb, or ccc }.
To construct an NFA for this language, we can decompose it into three simpler languages: one for strings ending in 'a', one for strings ending in 'bb', and one for strings ending in 'ccc'. Then, we can combine these three NFAs using ε-transitions.
Here is the NFA for the given language:
css
Copy code
InitialState --a--> A --ε--> FinalState
--b--> B --b--> FinalState
--c--> C --c--> C --c--> FinalState
Explanation:
The InitialState is the starting state.
From the InitialState, there are three transitions labeled 'a', 'b', and 'c', leading to three separate paths.
Path 1: Transition 'a' leads to state A, which then transitions to the FinalState directly using an ε-transition. This path accepts strings ending in 'a'.
Path 2: Transition 'b' leads to state B, which then transitions to FinalState with another 'b' transition. This path accepts strings ending in 'bb'.
Path 3: Transition 'c' leads to state C, which then transitions to itself with two additional 'c' transitions. After three consecutive 'c' transitions, it reaches the FinalState. This path accepts strings ending in 'ccc'.
ii. Let Σ = {a, b, c, d, e}. Construct an NFA for the language L = { w ∈ Σ* | the letters in w are sorted alphabetically }.
To construct an NFA for this language, we can use a simple approach where each state represents a letter in the sorted alphabet. We start from the initial state and transition to the corresponding letter state when encountering that letter in the input string.
Here is the NFA for the given language:
css
Copy code
InitialState --a--> A --b--> B --c--> C --d--> D --e--> FinalState
Explanation:
The InitialState is the starting state.
From the InitialState, there are transitions labeled 'a', 'b', 'c', 'd', and 'e' that lead to their respective letter states.
The transitions follow the alphabetical order, where 'a' transitions to A, 'b' transitions to B, and so on.
The FinalState represents the end of the string.
iii. Let Σ = {a, b, c, d, e}. Construct an NFA for the language { w ∈ Σ* | the last character of w appears nowhere else in w, and |w| > 1 }.
To construct an NFA for this language, we can use a simple approach where each state represents a letter in the alphabet. We transition from the initial state to the letter states based on the input string, and then transition to the final state only if the last character appears nowhere else in the string.
Here is the NFA for the given language:
css
Copy code
InitialState --a--> A --a--> RejectState
--b--> B --b--> RejectState
--c--> C --c--> RejectState
--d--> D --d--> RejectState
--e--> E --e--> RejectState
Explanation:
The InitialState is the starting state.
From the InitialState, there are transitions labeled 'a', 'b', 'c', 'd', and 'e' that lead to their respective letter states.
Each letter state transitions to the RejectState if it encounters the same letter again, indicating that the last character appears

Consider the following graph to answer the questions? loglaal memory 3. The logical address of \( k \) is equal? a) Page no \( =2 \), offset no. \( =2 \) b) Page no \( =2 \), offset no \( =3 \) c) Pag
The given image represents a paging scheme used in virtual memory. The virtual memory or logical address is divided into two parts: page number and offset. The page number is used to identify the page while the offset is used to identify the location within the page.
To solve the given question, we need to know the memory allocation for the given virtual memory address. From the graph, we can see that the virtual address has 3 bits to represent the offset. Thus, the offset can range from 000 to 111, i.e., 0 to 7 in decimal.
Similarly, the virtual address has 2 bits to represent the page number. Thus, the page number can range from 00 to 11, i.e., 0 to 3 in decimal.
Given that the logical address of k is 0100 0010. Here, the leftmost 2 bits represent the page number while the remaining 3 bits represent the offset. Thus, the page number for this logical address is 01 which is equivalent to 1 in decimal. Similarly, the offset for this logical address is 010 which is equivalent to 2 in decimal.
Hence, the logical address of k is equal to option (a) Page no =2, offset no. =2.

please explain the principle difference between the channel
selection process in phase division multiplex (PDM), and code
division multiple access (CDMA).
The main difference between the channel selection process in Phase Division Multiplexing (PDM) and Code Division Multiple Access (CDMA) lies in the technique used to allocate channels or codes to different users.
In PDM, multiple users share a single transmission channel by dividing it into different time slots and assigning each user a dedicated slot. This means that each user is assigned a specific time slot during which they can transmit their data over the shared channel. The receiver must know when to expect the data from each user and switch to the appropriate time slot to receive it. Therefore, the channel selection process in PDM is based on time division.
On the other hand, CDMA assigns a unique code to each user, which is then used to spread the signal over the entire bandwidth of the available channel. In other words, each user's signal is overlaid with a unique sequence of codes, and all the signals are transmitted simultaneously over the same frequency band. The receiver uses a matched filter, programmed with the same code as the transmitter, to extract the desired signal from the received waveform. Thus, the channel selection process in CDMA is based on code division.
In summary, the principle difference between the channel selection process in PDM and CDMA is that PDM allocates different time slots to different users, while CDMA assigns unique codes to each user and transmits all signals simultaneously over the same frequency band.

f
To add a loop to rename the zip folder and the "INDEX.dat" file in PowerShell 4, you can use the following code:
```powershell
$zipFile = "C:\path\to\zipfile.zip"
$indexFile = "C:\path\to\INDEX.dat"
# Check if the zip file exists
if (Test-Path $zipFile -PathType Leaf) {
$counter = 1
$zipFileBase = [System.IO.Path]::GetFileNameWithoutExtension($zipFile)
$newZipFile = "$zipFileBase$counter.zip"
# Increment the counter until a unique zip file name is found
while (Test-Path $newZipFile -PathType Leaf) {
$counter++
$newZipFile = "$zipFileBase$counter.zip"
}
Rename-Item -Path $zipFile -NewName $newZipFile
}
# Check if the index file exists
if (Test-Path $indexFile -PathType Leaf) {
$counter = 1
$indexFileBase = [System.IO.Path]::GetFileNameWithoutExtension($indexFile)
$newIndexFile = "$indexFileBase$counter.dat"
# Increment the counter until a unique index file name is found
while (Test-Path $newIndexFile -PathType Leaf) {
$counter++
$newIndexFile = "$indexFileBase$counter.dat"
}
Rename-Item -Path $indexFile -NewName $newIndexFile
}
```
The code begins by defining the paths to the zip file and the "INDEX.dat" file. It then checks if each file exists using the `Test-Path` cmdlet. If the zip file exists, it initializes a counter and extracts the base file name without the extension using the `GetFileNameWithoutExtension` method. It appends the counter to the base name until a unique zip file name is found, and then renames the original zip file using `Rename-Item`.
Similarly, if the index file exists, it follows the same process of incrementing the counter and finding a unique name by appending the counter to the base name. Finally, it renames the original index file using `Rename-Item`.
This code ensures that if a zip file or an index file already exists, a unique name with an incremental counter is assigned to avoid overwriting existing files.
The provided PowerShell code adds a loop to rename the zip folder and the "INDEX.dat" file with an incremental counter to ensure uniqueness. It checks if the files already exist and appends a counter to the base name until a unique name is found. The code then renames the files accordingly. By incorporating this loop, the script ensures that the files are renamed with distinct names to prevent any data loss or overwrite scenarios.

Using the convolutional code and Viterbi algorithm, assuming that the encoder and decoder always start in State 0, what is the output string generated for the input sequence 00101101?
1) 00 11 10 01 01 01 00
2) 00 00 11 10 00 01 01 00
3) 00 11 10 00 01 01 00 10
4) 00 10 11 10 00 01 01 00
5) None of the above.
Option (3) is the correct answer. Convolutional codes are a type of error-correcting codes that use feedback shift registers to encode the input data.
The Viterbi algorithm is a maximum-likelihood decoding algorithm used to decode convolutional codes by finding the most probable path through the trellis diagram.
Assuming a rate-1/2 convolutional code with generator polynomials (5, 7) and (7, 5), the output string generated for the input sequence 00101101 starting in State 0 using the Viterbi algorithm can be determined as follows:
Convert the input sequence into binary format: 0 0 1 0 1 1 0 1
Encode the input sequence using the convolutional encoder, starting in State 0. The encoded sequence is obtained by passing each input bit through the encoder and generating two output bits based on the current state of the encoder. The resulting encoded sequence is: 00 11 10 11 00 10 01 10.
The Viterbi algorithm uses the trellis diagram to find the most probable path from State 0 to the final state. The algorithm compares the received sequence with all possible paths through the trellis and chooses the path with the highest likelihood based on the Hamming distance between the received sequence and the candidate paths.
Starting in State 0, the algorithm calculates the Euclidean distances between the received bits and the expected bits at each state, and selects the shortest path at each stage. This results in the decoded sequence: 00 11 10 00 01 01 00 10.
Therefore, option (3) is the correct answer. The Viterbi algorithm is an important tool in decoding convolutional codes, especially in applications such as satellite communication and digital storage systems where high data rates and low error rates are required.

Recurring staff training to maintain security awareness and instill secure practices
Questions:
1) Identify places in the factory’s information systems where encryption should be implemented and identify the preferred use of private (symmetric) and public (asymmetric) keys. Describe a key management system.
2) List and briefly describe the steps the factory human resources staff should take to minimize security risks associated with company personnel.
1) Encryption should be implemented in the following areas of the factory's information systems: a) Secure wide area networking: Encryption should be used to protect data transmitted over the network between the factory and other company facilities, materials suppliers, customers, and transportation providers.
This can be achieved by implementing secure protocols such as SSL/TLS (Transport Layer Security) for data encryption during transmission.
b) Storage of sensitive data: Encryption should be applied to sensitive data at rest, such as product design data, manufacturing process data, human resources data, customer data, and financial and planning data. This ensures that even if the data is compromised or stolen, it remains unreadable without the appropriate decryption key.
c) Secure backup: Data backups should be encrypted to protect against unauthorized access or tampering. This is particularly important to defeat or minimize ransomware threats.
The preferred use of private (symmetric) and public (asymmetric) keys in encryption depends on the specific use case. Symmetric encryption is more efficient and faster but requires a shared key for encryption and decryption. Asymmetric encryption uses a public key for encryption and a private key for decryption, providing stronger security but with higher computational overhead.
For secure wide area networking and secure backup, symmetric encryption can be used since both the factory and the authorized recipients of the data can share the same encryption key securely. Asymmetric encryption, on the other hand, should be used for securing the storage of sensitive data, where each recipient has a unique private key to decrypt the data encrypted with the corresponding public key.
A key management system should be implemented to securely generate, store, distribute, and revoke encryption keys. This system should include mechanisms for securely storing private keys, securely sharing public keys, and periodically rotating encryption keys to enhance security. Key management processes should also cover procedures for key generation, key distribution, key revocation, and key recovery in case of key loss or compromise.
2) The factory's human resources staff should take the following steps to minimize security risks associated with company personnel:
a) Background checks: Conduct thorough background checks for job applicants to verify their identities, qualifications, and integrity. This helps identify potential security risks and ensures that trustworthy individuals are hired.
b) Secure onboarding and offboarding: Implement a well-defined process for employee onboarding and offboarding. This process should include granting and revoking access privileges to systems, applications, and sensitive data based on the principle of least privilege. Timely removal of access rights for departing employees is crucial to prevent unauthorized access.
c) Security training and awareness: Provide recurring security training for all employees to educate them about security best practices, potential risks, and their responsibilities in maintaining a secure work environment. Testing and measuring training effectiveness can help identify areas that require additional focus.
d) Insider threat detection: Implement tools and procedures to detect and mitigate insider threats. This includes monitoring employee activities, access logs, and behavior patterns to identify any suspicious or unauthorized activities. Regular security audits and reviews can help detect anomalies and potential security breaches.
e) Employee security understanding: Ensure that employees have a clear understanding of the company's security policies and procedures. This can be achieved through periodic security awareness campaigns, reminders, and ongoing communication about the importance of security practices.
By following these steps, the factory's human resources staff can contribute to minimizing security risks associated with company personnel and create a culture of security awareness throughout the organization.

It is typically assumed that parameter passing during procedure calls takes constant time, even if an N-element array is being passed. This assumption is valid in most systems because a pointer to the array is passed, not the array itself. Examine the parameter passing strategy below:
-An array is passed by pointer. Time = Θ(1).
For the above parameter-passing strategy, calculate the complexity for the MergeSort pseudocode below. Assume that declarations of L and R take O(1) time. function MergeSort (A[1:N]) DECLARE: L=A[1:F100r(N/2)] DECLARE: R=A[(F100r(N/2)+1):N] L= MergeSort (L) R= MergeSort (R) RETURN ( MergeSorted (L,R))
The complexity of the MergeSort pseudocode using the given parameter-passing strategy is Θ(N log N). The strategy of passing the array by a pointer, which takes constant time, does not affect the overall time complexity of the MergeSort algorithm.
The time complexity is determined by the recursive calls to MergeSort and the merging of subarrays, which together contribute to the Θ(N log N) complexity.
The MergeSort algorithm divides the input array into two halves, recursively applies MergeSort to each half, and then merges the sorted halves. In the given parameter-passing strategy, the array A is passed by a pointer, which takes constant time (Θ(1)).
The pseudocode declares two new arrays, L and R, and assigns them the values of the left and right halves of A, respectively. The time complexity of these declarations is assumed to be constant (O(1)).
Then, the MergeSort function is recursively called on arrays L and R, which results in two recursive calls. These calls are made on arrays that are approximately half the size of the original array A. The time complexity of the recursive calls can be represented by the recurrence relation T(N) = 2T(N/2), which corresponds to the divide step of the MergeSort algorithm. This recurrence relation has a solution of Θ(N log N).
Finally, the MergeSorted function is called to merge the sorted subarrays L and R. The merging operation takes linear time (Θ(N)), as it iterates through the elements of both subarrays and compares and combines them to produce a sorted merged array.
Considering all these steps together, the time complexity of the MergeSort pseudocode using the given parameter-passing strategy is Θ(N log N). The constant time taken for passing the array by a pointer does not affect the overall time complexity, which is determined by the recursive calls and merging step.

In this program, we define a user class that has three attributes: username, password, and role. We initialize three User objects with different usernames, passwords, and roles. The program prompts the user to input their username and password. It then checks if the entered credentials match any of the users in the users list. If a match is found, it sets the authenticated flag to True and prints a welcome message with the username. If no match is found, it prints an access denied message.
You can run this program and test the login functionality by entering different usernames and passwords. If the entered credentials match one of the users, you will see the welcome message. Otherwise, you will see the access denied message.The core of extensible programming is defining functions.
