An online game is played with two dice. In this context, explain what is meant by decomposition in a simple way.

Their value is random, so you need to generate two numbers between 1 & 6.
You may need to display the numbers
The main part of the program needs to know the numbers to limit what the user may do next.

That's most of the first level of decomposition. You need to keep decomposing (breaking into smaller simpler pieces) (think of an outline) and deciding what objects, functions, data structures and logic you're going to code this.

#Write a function called string_finder. string_finder should #take two parameters: a target string and a search string. #The fun

adoni [48]

Answer:

I am writing a Python program:

def string_finder(target,search): #function that takes two parameters i.e. target string and a search string

position=(target.find(search))# returns lowest index of search if it is found in target string

if position==0: # if value of position is 0 means lowers index

return "Beginning" #the search string in the beginning of target string

elif position== len(target) - len(search): #if position is equal to the difference between lengths of the target and search strings

return "End" # returns end

elif position > 0 and position < len(target) -1: #if value of position is greater than 0 and it is less than length of target -1

return "Middle" #returns middle

else: #if none of above conditions is true return not found

return "not found"

#you can add an elif condition instead of else for not found condition as:

#elif position==-1

#returns "not found"

#tests the data for the following cases

print(string_finder("Georgia Tech", "Georgia"))

print(string_finder("Georgia Tech", "gia"))

print(string_finder("Georgia Tech", "Tech"))

print(string_finder("Georgia Tech", "Idaho"))

Explanation:

The program can also be written in by using string methods.

def string_finder(target,search): #method definition that takes target string and string to be searched

if target.startswith(search): #startswith() method scans the target string and checks if the (substring) search is present at the start of target string

return "Beginning" #if above condition it true return Beginning

elif target.endswith(search): #endswith() method scans the target string and checks if the (substring) search is present at the end of target string

return "End" #if above elif condition it true return End

elif target.find(search) != -1: #find method returns -1 if the search string is not in target string so if find method does not return -1 then it means that the search string is within the target string and two above conditions evaluated to false so search string must be in the middle of target string

return "Middle" #if above elif condition it true return End

else: #if none of the above conditions is true then returns Not Found

return "Not Found"

Gennadij [26K]

Answer:

She should join the Future Business Leaders of America–Phi Beta Lambda

Explanation:

CTSOs are Career and technical student organizations. These organizations are vocational and extracurricular groups based primarily in high schools, colleges and career technological centres, for students in Career and Technical Education. They are important parts of the high school and college programs.

The Future Business Leaders of America–Phi Beta Lambda prepares students to become community-minded business leaders. It provides opportunities to learn career skills and gain leadership experience.

Therefore Adele should pick this CTSO

g Suppose the information content of a packet is the bit pattern 1110 0110 1001 1101 and an even parity scheme is being used. Wh

erma4kov [3.2K]

Answer: see description

Explanation:

first we accommodate the bit pattern in a matrix of 4x4 which is the minimum length checksum field, now with even parity two-dimensional scheme we need to complete this matrix by adding one row and one column by adding at the end of each row a 1 or a 0 to complete pairs of 1's:

we have

$\left[\begin{array}{cccc}1&1&1&0\\0&1&1&0\\1&0&0&1\\1&1&0&1\end{array}\right]$

so we complete with this, adding a row at the end which matches a pair number of 1's

$\left[\begin{array}{ccccc}1&1&1&0&1\\0&1&1&0&0\\1&0&0&1&0\\1&1&0&1&1\\1&1&0&0&0\end{array}\right]$

Write a program to declare a matrix A[][] of order (MXN) where ‘M’ is the number of rows and ‘N’ is the

Liula [17]

Answer:

import java.io.*;

import java.util.Arrays;

class Main {

public static void main(String args[])

throws IOException{

// Set up keyboard input

InputStreamReader in = new InputStreamReader(System.in);

BufferedReader br = new BufferedReader(in);

// Prompt for dimensions MxN of the matrix

System.out.print("M = ");

int m = Integer.parseInt(br.readLine());

System.out.print("N = ");

int n = Integer.parseInt(br.readLine());

// Check if input is within bounds, exit if not

if(m <= 2 || m >= 10 || n <= 2 || n >= 10){

System.out.println("Matrix size out of range.");

return;

}

// Declare the matrix as two-dimensional int array

int a[][] = new int[m][n];

// Prompt for values of the matrix elements

System.out.println("Enter elements of matrix:");

for(int i = 0; i < m; i++){

for(int j = 0; j < n; j++){

a[i][j] = Integer.parseInt(br.readLine());

}

// Output the original matrix

System.out.println("Original Matrix:");

printMatrix(a);

// Sort each row

for(int i = 0; i < m; i++){

Arrays.sort(a[i]);

}

// Print sorted matrix

System.out.println("Matrix after sorting rows:");

printMatrix(a);

}

// Print the matrix elements separated by tabs

public static void printMatrix(int[][] a) {

for(int i = 0; i < a.length; i++){

for(int j = 0; j < a[i].length; j++)

System.out.print(a[i][j] + "\t");

System.out.println();

}

Explanation:

I fixed the mistake in the original code and put comments in to describe each section. The mistake was that the entire matrix was sorted, while only the individual rows needed to be sorted. This even simplifies the program. I also factored out a printMatrix() method because it is used twice.
