For the given complete binary tree (given in an array), Convert it into a max heap
To convert the given complete binary tree in an array to a max heap, we need to follow the max heapify algorithm. This is the algorithm that helps us convert a binary tree to a max heap.
To convert a binary tree into a max heap, we need to start by comparing the root node to its children. If the root node is greater than both of its children, we are done. However, if the root node is smaller than one of its children, we need to swap the root node with the child that has the greater value. Next, we repeat the same process on the subtree rooted at the child that we swapped the root node with. This process is repeated until we have a complete max heap. The algorithm can be broken down into the following steps: Compare the root node to its children.If the root node is smaller than one of its children, swap it with the child that has the greater value. Repeat the above step on the subtree rooted at the child that we swapped the root node with. Repeat the entire process until we have a complete max heap. Therefore, to convert the given complete binary tree in an array to a max heap, we must use the max heapify algorithm, which is a simple, efficient, and effective algorithm that can be used to convert a binary tree into a max heap.

Critical thinking skills are necessary in the event of an unforeseen situation that requires the supervisor to make an immediate decision.All these attributes and more are necessary for one to become a successful supervisor.
To become a successful supervisor, you must possess a range of traits that include good communication, leadership, delegation, and critical thinking skills. A supervisor must also have strong work ethics, be proactive, goal-oriented, able to motivate others, and have the ability to adapt to changing environments.Supervision requires constant communication between subordinates and supervisors. Being an excellent communicator, one of the key skills that a supervisor should possess, helps in relaying clear instructions and expectations and avoiding misunderstandings. For instance, if an employee fails to understand a task that they are supposed to complete, the supervisor must clearly and effectively communicate the task to avoid confusion and errors in the future.Moreover, the ability to delegate tasks efficiently is another key attribute of a successful supervisor. Delegation requires the supervisor to identify employees' strengths and weaknesses to determine which tasks they can perform most efficiently. This leads to a more productive workforce, as tasks are assigned based on individual strengths and expertise.A successful supervisor must also possess strong leadership skills, which involve guiding, directing, and motivating subordinates towards a common goal. The supervisor's primary role is to set goals and targets, establish objectives, and facilitate the team to work towards achieving these targets. The supervisor must also be able to identify their employees' motivations and then find ways to leverage them.Finally, a successful supervisor must possess strong critical thinking skills.

The program dfbf traverses a graph breadth-first and computes distances from the root to reachable nodes; it then traverses the graph depth-first and determines whether the graph from root is cyclic.
What is BFS? Breadth-first search (BFS) is a graph traversal algorithm that visits all vertices of a graph in breadth-first order, i.e., it visits vertices at the same level first before moving on to vertices at the next level. What is DFS? Depth-first search (DFS) is a graph traversal algorithm that visits all vertices of a graph in depth-first order, i.e., it visits vertices at the maximum depth first before backtracking.
It is usually implemented using a stack and recursion.## Given program for DFS and BFS: import sys

Be detailed in your answer. Explain what the task is and how you would implement and test it.
As a System Administrator, we have used the command prompt for many tasks throughout the semester. What are 3 main command prompt utilities you believe you would use in this role and when would you use them?
As a security personnel responsible for the data of 100 users in an organization, one of the most important tasks to ensure the data is secured is encryption of the data. Encryption is the process of converting information into a code or cipher that is unreadable by unauthorized users. This makes it extremely difficult for hackers to access or steal sensitive information.
Implementing encryption ensures that in the event of a data breach, the information that has been compromised will not be of any use to hackers.Encryption can be implemented using various methods such as disk encryption, email encryption, and file/folder encryption. In implementing encryption, the following steps can be taken:Data classification: This is the process of identifying the types of data that need to be encrypted. The security personnel should identify the most sensitive data and encrypt it. Implementation of encryption tools: There are various encryption tools that can be used. For instance, BitLocker, VeraCrypt, and AxCrypt are encryption tools that can be used for disk, file/folder, and email encryption respectively.Testing: After implementing encryption, it is important to test the encryption tools to ensure that they are functioning optimally. This can be done through penetration testing, which involves attempting to hack into the system using various methods to ensure that the data is secure.Using command prompt utilities is an important aspect of a System Administrator's role.
Three main command prompt utilities that are essential for a System Administrator include:1. Ping: This utility is used to test connectivity between two devices on a network. It is useful when troubleshooting network connectivity issues.2. Ipconfig: This utility is used to display the IP configuration of a device. It displays information such as the IP address, subnet mask, and default gateway. It is useful when troubleshooting network connectivity issues.3. Netstat: This utility is used to display active network connections, including listening ports and associated protocols. It is useful when troubleshooting network connectivity and security issues.

Ceylon Steel produces steel alloy plates. The firm wants to locate a central distribution center in the northern province of the country that will serve all of its regional centers. The firm evaluated five locations (Jaffna, Kilinochchi, Mannar, Mullaitivu, Vavuniya), and using the center of gravity method narrowed down its choice to Jaffna. The firm's supply chain manager is facing a decision regarding the amount of space to lease for the Jaffna distribution center for the upcoming three-year period. Forecasts indicate that the Jaffna distribution center will need to handle a demand of 100,000 steel alloy plates for each of the next 3 years; the firm's distribution center requirements are 1,000 square feet of distribution center space for every 1,000 steel alloy plates. The firm receives a revenue of $1.22 for each steel alloy plate. The supply chain manager must decide whether to sign a three-year lease or obtain the distribution center space on the spot/cash market each year (assuming that the only cost that the firm faces is the cost of the distribution center). The three-year lease will cost $1 per square foot per year, and the spot/cash market rate is expected to be $1.10 per square foot per 1 year for each of the three years. The firm has a discount rate of k=0.2. Should the supply chain manager sign a lease?
To determine whether the supply chain manager should sign a lease for the Jaffna distribution center, we need to compare the total costs of signing a three-year lease versus obtaining the distribution center space on the spot/cash market each year.
First, let's calculate the total cost of signing a three-year lease: Lease cost per year = $1 per square foot
Distribution center space required per year = (100,000 steel alloy plates / 1,000) * 1,000 square feet = 100,000 square feet Total lease cost for 3 years = Lease cost per year * Distribution center space required per year * 3 years = $1 * 100,000 square feet * 3 years = $300,000 Next, let's calculate the total cost of obtaining the distribution center space on the spot/cash market each year: Spot/cash market rate per year = $1.10 per square foot
Total spot/cash market cost for 3 years = Spot/cash market rate per year * Distribution center space required per year * 3 years = $1.10 * 100,000 square feet * 3 years = $330,000
Now, we need to calculate the present value of both options using the discount rate:
Present value of lease cost = $300,000 / (1 + 0.2)^3 = $185,185
Present value of spot/cash market cost = $330,000 / (1 + 0.2)^1 + $330,000 / (1 + 0.2)^2 + $330,000 / (1 + 0.2)^3 = $247,934
Comparing the present values, we find that the present value of the lease cost is lower than the present value of the spot/cash market cost. Therefore, based on the calculations and assuming that the only cost is the distribution center, the supply chain manager should sign a three-year lease for the Jaffna distribution center as it results in lower total costs over the three-year period.

i. Convert the Octal number $366_8$ to decimal.
ii. Convert the decimal number $\mathbf{2 4 4}$ to binary.
iii. Convert the binary 10101101 to hexadecimal number.
iv. Convert the hexadecimal number $\mathbf{7 A}$ to octal.
v. Convert the decimal number -92 to binary using 8-bit sign and magnitude representation.
Here are the solutions to the given problems: (i) Given, Octal number $366_8$ To convert Octal to decimal we need to follow the below formula:$\large {\color{Blue} {Decimal}} = \sum_{i=0}^{n-1} \left(Octal_i \times 8^i \right)$ Now, let's find the decimal value of the given octal value. $366_8$ can be written as $3 \times 8^2 + 6 \times 8^1 + 6 \times 8^0$= $3 \times 64 + 6 \times 8 + 6 \times 1$= $192 + 48 + 6$= $\boxed{246}$
Therefore, the decimal value of Octal $366_8$ is $\boxed{246}$.(ii) Given, Decimal number $\mathbf{2 \:4 \:4}$To convert Decimal to Binary we need to follow the below process: We need to divide the given decimal number by 2 until the quotient is 0. Then, we need to list the remainder of each division starting with the most recent remainder at the bottom. For example: Decimal = 10$\div$ 2 = 5, Remainder = 0$\div$ 2 = 0, Remainder = 1$0 \: \: 1 \: \: 0 \: \: 1 \: \: 1_2$Therefore, the Binary equivalent of the Decimal number $\mathbf{2 \:4 \:4}$ is $\boxed{11110011_2}$.(iii) Given, Binary number 10101101
To convert Binary to Hexadecimal we need to follow the below process: We need to take the binary number and group them from the right side into groups of 4 bits. For the groups that are not 4 bits long, we add zeroes at the left. Then, we convert each 4-bit binary group to its equivalent hexadecimal value. After that, we concatenate these equivalent hexadecimal values to get the equivalent hexadecimal number. For example: $1 \: 0 \: 1 \: 0 \: 1 \: 1 \: 0 \: 1_2$ = $1 \: 0 \: 1 \: 0_2$ and $ \: 1 \: 1 \: 0 \: 1_2$= $A \: D_{16}$ Therefore, the Hexadecimal equivalent of the Binary number $10101101_2$ is $\boxed{AD_{16}}$.(iv) Given, Hexadecimal number $\mathbf{7 \: A}$To convert Hexadecimal to Octal we need to follow the below process: We need to convert the hexadecimal number to equivalent Binary. Then, we group the binary digits into groups of 3 bits from the right side. Then, we convert each group of 3 bits to its equivalent octal value. After that, we concatenate these equivalent octal values to get the equivalent octal number. For example: Hexadecimal = $\mathbf{7 \: A}$ = $0111 \: 1010_2$ $\: 011 \: 110 \: 100_2$ = $3 \: 6 \: 4_8$

Can you use clustering to analyze the heating cost of your house in relation to outside temperature? (Y/N) Explain your choice with some terms and concepts common to Data Science.
Yes, clustering can be used to analyze the heating cost of a house in relation to outside temperature. Clustering is a popular unsupervised learning technique in data science that groups similar data points together based on their characteristics.
In this case, we can apply clustering to identify patterns and relationships between heating costs and outside temperatures. By collecting historical data on heating costs and corresponding outside temperatures, we can create a dataset where each data point represents a specific time period with its associated heating cost and temperature. We can then apply clustering algorithms such as K-means or hierarchical clustering to group similar data points together based on their heating costs and temperature values. This allows us to identify different clusters or segments that exhibit similar heating cost patterns in relation to outside temperature.
Analyzing these clusters can provide valuable insights. For example, we may discover a cluster where heating costs are high during colder months, indicating poor insulation. Alternatively, we may find a cluster where heating costs are consistently low, suggesting energy-efficient insulation. By understanding these patterns, homeowners can make informed decisions to optimize their heating systems and improve energy efficiency. In summary, clustering helps uncover hidden patterns and relationships between heating costs and outside temperatures, allowing for data-driven decision-making to reduce energy consumption and costs.

SRAM requires refresh PLDs consist of programmable combinational logic elements Maximum delay of the combinational circuit the connects the output of one register to the input of the other determines the operating clock frequency Adding more registers to the instruction set should not increase the instruction width Flip-Flops are typically not used in the implementation of memory systems because they are not fast enough A good design practice is to use non-blocking assignments when you are modeling both sequential and combinational logic The propagation time in a Flip-Flop needs to be larger than the hold time.
Here are the answers to your given terms: Clock skew could cause failures in the combinational logic circuits: Clock skew is a phenomenon in synchronous digital circuits where the clock signal that reaches different components of the circuit arrives at different times. CLK skew could cause failures in combinational logic circuits.
A clock skew failure happens when two signals should occur simultaneously, but one signal comes after the other. CLB can be configured as RAM: RAM and ROM blocks are configurable logic blocks (CLBs) used in FPGA design. You can configure a CLB to operate as a memory element and store data. SRAM requires refresh: SRAM stands for Static Random-Access Memory. SRAM chips are faster and more expensive than DRAM chips. SRAM doesn't need to be refreshed like DRAM.PLDS consist of programmable combinational logic elements: A programmable logic device (PLD) is a type of digital circuit that can be programmed to carry out various logic operations.
It consists of programmable logic elements, such as a programmable array logic (PAL), a programmable logic array (PLA), and a field-programmable gate array (FPGA).Maximum delay of the combinational circuit that connects the output of one register to the input of the other determines the operating clock frequency: The maximum delay of the combinational circuit connecting one register's output to another register's input is determined by the operating clock frequency.Adding more registers to the instruction set should not increase the instruction width: By adding registers to the instruction set, you do not increase the instruction width.Flip-flops are typically not used in the implementation of memory systems because they are not fast enough: Flip-flops are not used in the implementation of memory systems because they are not fast enough to implement memory elements, and they have high power dissipation.A good design practice is to use non-blocking assignments when you are modeling both sequential and combinational logic: Non-blocking assignments are a good design practice when modeling both sequential and combinational logic.The propagation time in a Flip-Flop needs to be larger than the hold time: The propagation delay of the input signal through the Flip-flop is the amount of time it takes for the signal to pass through the Flip-flop, whereas the hold time is the amount of time the input signal must be stable after the clock edge. To ensure reliable operation, the Flip-flop's propagation time must be greater than the hold time.

You should be able to answer this question after you have studied Unit 7. For each of the statements below, identify whether the statement is true, or false, and write a brief explanation why, clearly explaining the terms you use.
(a) $(2$ marks)
Finding the prime factors of an integer is computable.
(b) $(2$ marks $)$
Finding the prime factors of an integer is always in the class $P$.
(c) $(2$ marks)
Deciding whether two programs produce exactly the same outputs for the same inputs is decidable.
(d) $(2$ marks)
Deciding whether a given program will terminate for every possible input is undecidable.
(a) True. Finding the prime factors of an integer is computable. This means that there exists an algorithm that, given an integer as input, can determine its prime factors.
One such algorithm is the trial division method, which systematically divides the number by prime numbers to check if they are factors. If a prime number is found to be a factor, it is added to the list of prime factors.
This process continues until the number is fully factored. The algorithm will terminate and provide the prime factors for any input integer, making it computable.
(b) False. Finding the prime factors of an integer is not always in the class P. The class P refers to the set of problems that can be solved in polynomial time.
While there are efficient algorithms for factoring small numbers, such as the trial division or Pollard's rho algorithm, factoring large numbers becomes significantly harder.
The best known factoring algorithm for large integers, the General Number Field Sieve (GNFS), has a sub-exponential time complexity. Therefore, factoring is not considered a problem in class P.
(c) True. Deciding whether two programs produce exactly the same outputs for the same inputs is decidable. This means that there exists an algorithm that, given two programs and their inputs, can determine if they produce the same outputs.
One way to achieve this is by running both programs with the same inputs and comparing the resulting outputs. If the outputs are identical, the algorithm returns true; otherwise, it returns false.
This process can be performed for any given programs and inputs, making the problem decidable.
(d) False. Deciding whether a given program will terminate for every possible input is undecidable. This problem is known as the Halting Problem, and it was proven undecidable by Alan Turing in 1936.
The proof shows that there cannot exist a general algorithm that can determine, for any given program and input, whether the program will eventually halt or run indefinitely.
The undecidability of the Halting Problem has profound implications in computer science, as it limits the extent to which we can analyze the behavior of arbitrary programs.

d) Which stakeholder holds the most responsibility in bridging the gap of the digital divide? What are some measuring this stakeholder can take to bridge this gap? (2.5 marks)
a) Comparative relationship between Ethical Egoism and Kant’s Categorical Imperative (Second Formulation):Ethical Egoism is the belief that individuals ought to do whatever it is that satisfies their self-interest. Ethical egoism is often used interchangeably with individualism. Kant's categorical imperative, on the other hand, is the belief that every moral action should be done from a sense of duty, regardless of its consequences.
The second formulation of Kant's Categorical Imperative states that individuals should always treat other people as an end in themselves, rather than as a means to an end. So, the second formulation of Kant's Categorical Imperative is opposed to Ethical Egoism because it advocates for actions that benefit others, even if it may be disadvantageous to the individual.b) How a compromised peer-review process for academic publications impacts the public trust in publication platforms?Trust Issues of Unethical Peer Review Process:Loss of public trust: This is the most significant impact of a compromised peer-review process.

We want to write a program that accepts a file called pets.txt containing information about the number of pets different people have. pets.txt has the following contents:
Andrew has 5 dogs Julian has 62 pugs Isabella has 6 sheep
Our job is to write a method called numConvert, which will take a Scanner parameter for the input file, a PrintStream parameter for the output file, and a Scanner parameter for the console Scanner.
The method will convert each numerical number into a number written in letters, while preserving the contents of the rest of the file, and output the modified file to a file called output.txt. After running our program, output.txt should contain the following:
Andrew has five dogs
Julian has sixty two
pugs Isabella has six sheep
The way we will do this is by prompting the user to type in each number as a lettered word each time an integer number is found in the tokens of the input file. Using pets.txt, the program should prompt the user with the following:
The user input from console is bold in the example above.
import java.util.*;
import java.io.*;
public class Pets {
public static void main(String[] args) throws FileNotFoundException {
Scanner console = new Scanner(System.in);
String inputFile = "pets.txt";
File file = new File(inputFile);
Scanner scanLine = new Scanner(file);
PrintStream output = new PrintStream(new File("output.txt"));
numConvert(scanLine, output, console);
}
We are required to write a method called numConvert, which will take a Scanner parameter for the input file, a PrintStream parameter for the output file, and a Scanner parameter for the console Scanner. The method will convert each numerical number into a number written in letters, while preserving the contents of the rest of the file, and output the modified file to a file called output.txt.To achieve this, we will have to read each line of pets.txt, one at a time, and tokenize each line using space as a delimiter.
This will give us an array of strings, each of which contains a tokenized part of the line.Then, we will loop through this array of strings and check if any of them contain numerical digits. If so, we will prompt the user to enter the corresponding lettered word for that number. Once we have the lettered word, we will replace the numerical digits in the array with the corresponding word.After the loop is finished, we will join the array back into a single string, separated by spaces, and output it to the output file using the PrintStream object given as a parameter to the method. Here is the implementation of the numConvert method:public static void numConvert(Scanner scanLine, PrintStream output, Scanner console) {while (scanLine.hasNextLine()) {String line = scanLine.nextLine();String[] tokens = line.split(" ");for (int i = 0; i < tokens.length; i++) {if (tokens[i].matches("\\d+")) {System.out.print("Enter word for " + tokens[i] + ": ");String word = console.nextLine();tokens[i] = word;}String modifiedLine = String.join(" ", tokens);output.println(modifiedLine);}We can call this method from the main method as follows:public static void main(String[] args) throws FileNotFoundException {Scanner console = new Scanner(System.in);String inputFile = "pets.txt";File file = new File(inputFile);Scanner scanLine = new Scanner(file);PrintStream output = new PrintStream(new File("output.txt"));numConvert(scanLine, output, console);}The numConvert method reads the pets.txt file using the Scanner object scanLine, and writes the modified output to the file "output.txt" using the PrintStream object output.
It prompts the user for input using the Scanner object console. The main method creates the Scanner, PrintStream, and Scanner objects, and calls the numConvert method with these objects as parameters. The output file "output.txt" will contain the modified contents of the input file, with all numerical digits converted to their lettered form.

The following steps explain how you can use the A* algorithm and a graph to create a pathfinding system for the boss to follows:
1. Create a Graph:Create a graph with nodes that represent areas that the boss can move on. The edges represent the connection between nodes. The boss can only move on edges and nodes that are connected. Each edge has a weight, which represents the distance between two nodes.
2. Implement the A* Algorithm:Use the A* algorithm to calculate the shortest path from the boss's current location to the player's location. The A* algorithm takes in the graph and two nodes, the start, and end node, as input. It then returns the shortest path between the two nodes.
3. Update the Boss's Location:Use the calculated path from the A* algorithm to update the boss's location. The boss should move from one node to the next along the path.
4. Repeat Steps 2 and 3:Repeat steps 2 and 3 every time the player moves to update the boss's location. This will ensure that the boss always follows the player through the shortest path.

1.Create a scilab program that would allow the user to input a number and the output would generate
even numbers from 0 up to the input. Example: Input = 11. Output: 0 2 4 6 8 10
2.. Create a scilab program that would compute the final grade and has the following inputs: a) 4 quiz b) final exam c) non board or board course. The output should get the final grade. Final grade is computed as follows 70% quiz, 30% final exam. The program will also determine if the students is under a non board or board program, if the student under a board course then the final grade would be base 0 otherwise the final grade would be base 40.
1. The scilab program that would allow the user to input a number and the output would generate even numbers from 0 up to the input:
In this case, we would make use of the modulo operation to determine if a number is even or odd. If a number is divisible by 2, the modulo operation would return 0, and that number is even. The Scilab code that would allow the user to input a number and output even numbers from 0 up to the input is shown below:
clear all;
clc;
a=input("Enter number:");
for i=0:1:a
if mod(i,2)==0
disp(i)
endif
endfor
The "clear all" command clears all previously defined variables and functions from Scilab's memory. The "clc" command clears Scilab's console. The input function is used to accept user input from the command window.
The for loop would execute as long as the value of the variable i is between 0 and a. The modulo operation is used to determine if a number is even or odd. If i modulo 2 is equal to 0, the number is even and would be displayed on the console.
2. The scilab program that would compute the final grade and has the following inputs: a) 4 quizzes b) final exam c) non-board or board course:
In this case, we would use a combination of Scilab's conditional statements and arithmetic operators to compute the final grade. The final grade is computed as follows: 70% quiz, 30% final exam.
The program would also determine if the student is under a non-board or board program. If the student is under a board course, then the final grade would be based on 0. Otherwise, the final grade would be based on 40. The Scilab code that would compute the final grade is shown below:
clear all;
clc;
quizzes = input("Enter score for the four quizzes [q1 q2 q3 q4]: ");
final_exam = input("Enter final exam score: ");
board_or_non_board = input("Enter 'board' or 'non-board': ", 's');
quiz_score = sum(quizzes);
quiz_percentage = quiz_score * 0.7;
final_percentage = final_exam * 0.3;
total_score = quiz_percentage + final_percentage;
if board_or_non_board == "board" then
final_grade = total_score
else
final_grade = total_score + 40
endif
disp(final_grade)

Create a program that finds anagrams within a txt file with multiple sentences . An anagram is two sentences that contain the same letters but in different order. The program should take each SENTENCE in a text file and find its anagram if there's one to find PROGRAM IN C LANGUAGE
This is a relatively complex task, so the program will be split into multiple steps: First, read the text file and store each sentence in a separate array. Then, for each sentence, generate all possible permutations of the letters and store them in a separate array. Next, compare each permutation array with all other permutation arrays to find any matches. If a match is found, print out the two sentences and mark them as anagrams.
Here's the program in C language:
```
#include
#include
#include
#define MAX_SENTENCES 100
#define MAX_LENGTH 100
void read_sentences(char sentences[][MAX_LENGTH], int *num_sentences, FILE *file) {
char line[MAX_LENGTH];
*num_sentences = 0;
while (fgets(line, MAX_LENGTH, file)) {
// remove trailing newline character
line[strcspn(line, "\n")] = 0;
// copy sentence into array
strcpy(sentences[*num_sentences], line);
(*num_sentences)++;
}
}
void generate_permutations(char *sentence, char **permutations, int *num_permutations, int length, int index) {
// base case: all letters have been used, add permutation to array
if (index == length) {
permutations[*num_permutations] = strdup(sentence);
(*num_permutations)++;
return;
}
// recursive case: generate permutations
for (int i = index; i < length; i++) {
// swap letters
char temp = sentence[index];
sentence[index] = sentence[i];
sentence[i] = temp;
// generate permutation for new sentence
generate_permutations(sentence, permutations, num_permutations, length, index + 1);
// swap letters back
temp = sentence[index];
sentence[index] = sentence[i];
sentence[i] = temp;
}
}
int compare_permutations(char **permutations1, int num_permutations1, char **permutations2, int num_permutations2) {
// compare each permutation in permutations1 with each permutation in permutations2
for (int i = 0; i < num_permutations1; i++) {
for (int j = 0; j < num_permutations2; j++) {
if (strcmp(permutations1[i], permutations2[j]) == 0) {
// permutations match, return true
return 1;
}
}
}
// no matches found, return false
return 0;
}
void find_anagrams(char sentences[][MAX_LENGTH], int num_sentences) {
// generate permutations for each sentence
char *permutations[MAX_SENTENCES][MAX_LENGTH * MAX_LENGTH];
int num_permutations[MAX_SENTENCES];
for (int i = 0; i < num_sentences; i++) {
num_permutations[i] = 0;
generate_permutations(sentences[i], permutations[i], &num_permutations[i], strlen(sentences[i]), 0);
}
// compare each sentence with all other sentences to find anagrams
for (int i = 0; i < num_sentences; i++) {
for (int j = i + 1; j < num_sentences; j++) {
if (compare_permutations(permutations[i], num_permutations[i], permutations[j], num_permutations[j])) {
// sentences are anagrams
printf("%s\n%s\n\n", sentences[i], sentences[j]);
}
}
}
}
int main() {
FILE *file = fopen("sentences.txt", "r");
if (file == NULL) {
printf("Error: could not open file.\n");
return 1;
}
char sentences[MAX_SENTENCES][MAX_LENGTH];
int num_sentences;
read_sentences(sentences, &num_sentences, file);
find_anagrams(sentences, num_sentences);
fclose(file);
return 0;
}
The main function first opens the text file and checks for any errors. It then declares an array of sentences and reads in the sentences from the text file using the read sentences function. Finally, it finds any anagrams using the find_ anagrams function and prints them out. The find anagrams function first generates all possible permutations of the letters for each sentence using the generate permutations function. It then compares each sentence with all other sentences using the compare permutations function to find any anagrams. If an anagram is found, the two sentences are printed out. Overall, this program should be able to find anagrams within a text file with multiple sentences using the C language.
