  R: array[1..nn] of integer;
  C: array[1..nm] of integer;
  i, j, n, m, k, s, a, b, p : integer;

begin

Answer 2

Task Description

You need to fill a two-dimensional array of size N*M with random integers. The range of these integers will be inputted from the keyboard. Then, you need to display the array on the screen. After that, you need to fill a one-dimensional array with the sum of the elements of each row of the two-dimensional array. Finally, you need to display the one-dimensional array on the screen. The same task should be done for the columns as well.

Solution

To solve this task, we can follow these steps:

1. Read the values of N and M from the user. 2. Read the range of the random integers from the user. 3. Create a two-dimensional array of size N*M. 4. Fill the two-dimensional array with random integers within the specified range. 5. Display the two-dimensional array on the screen. 6. Create a one-dimensional array of size N to store the sum of each row. 7. Calculate the sum of each row and store it in the one-dimensional array. 8. Display the one-dimensional array on the screen. 9. Repeat steps 6-8 for the columns.

Here's the code that implements the solution in Python:

import random

# Step 1: Read the values of N and M from the user
N = int(input("Enter the number of rows (N): "))
M = int(input("Enter the number of columns (M): "))

# Step 2: Read the range of the random integers from the user
min_range = int(input("Enter the minimum value for the random integers: "))
max_range = int(input("Enter the maximum value for the random integers: "))

# Step 3: Create a two-dimensional array of size N*M
array = [[0] * M for _ in range(N)]

# Step 4: Fill the two-dimensional array with random integers within the specified range
for i in range(N):
    for j in range(M):
        array[i][j] = random.randint(min_range, max_range)

# Step 5: Display the two-dimensional array on the screen
print("Two-dimensional array:")
for row in array:
    print(row)

# Step 6: Create a one-dimensional array of size N to store the sum of each row
row_sums = [0] * N

# Step 7: Calculate the sum of each row and store it in the one-dimensional array
for i in range(N):
    row_sums[i] = sum(array[i])

# Step 8: Display the one-dimensional array on the screen
print("Row sums:")
print(row_sums)

# Step 9: Repeat steps 6-8 for the columns
column_sums = [0] * M
for j in range(M):
    column_sums[j] = sum(array[i][j] for i in range(N))

print("Column sums:")
print(column_sums)

This code will prompt the user to enter the number of rows (N) and columns (M), as well as the range of the random integers. It will then generate a two-dimensional array filled with random integers within the specified range. After that, it will display the two-dimensional array on the screen. It will also calculate and display the sum of each row and column in separate one-dimensional arrays.
