🔷 C Program: Final Sum of Max Row and Min Column

#include <stdio.h>

int main()
{
    int n, m;
    printf("Enter the number of rows (N): ");
    scanf("%d", &n);
    printf("Enter the number of coloumns (M): ");
    scanf("%d", &m);

    int a[n][m];

    printf("Enter the elements of the array:\n");
    for (int i = 0; i < n; i++)
    {
        for (int j = 0; j < m; j++)
        {
            scanf("%d", &a[i][j]);
        }
    }

    int max_row_sum = 0;
    for (int i = 0; i < n; i++)
    {
        int row_sum = 0;
        for (int j = 0; j < m; j++)
        {
            row_sum += a[i][j];
        }
        if (i == 0 || row_sum > max_row_sum)
        {
            max_row_sum = row_sum;
        }
    }

    int min_col_sum = 0;
    for (int j = 0; j < m; j++)
    {
        int col_sum = 0;
        for (int i = 0; i < n; i++)
        {
            col_sum += a[i][j];
        }
        if (j == 0 || col_sum < min_col_sum)
        {
            min_col_sum = col_sum;
        }
    }

    int final_sum = max_row_sum + min_col_sum;
    printf("\nsum of row with highest sum: %d\n", max_row_sum);
    printf("sum of column with lowest sum: %d\n", min_col_sum);
    printf("Final sum (Largest row sum + smallest column sum): %d\n", final_sum);

📘 Explanation:

This C program works on a 2D array (matrix) and calculates two things:

🔹 Maximum Row Sum: The sum of the row which has the highest total.
🔹 Minimum Column Sum: The sum of the column which has the smallest total.

🔹 After collecting user input into the matrix, it traverses each row to find the maximum row sum.
🔹 Then it traverses each column to find the minimum column sum.
🔹 It adds both to compute the final_sum and displays all three values: max row sum, min col sum, and their sum.

🔍 Sample Output:

Enter the number of rows (N): 3
Enter the number of coloumns (M): 3
Enter the elements of the array:
1 2 3
4 5 6
7 8 9

sum of row with highest sum: 24
sum of column with lowest sum: 12
Final sum (Largest row sum + smallest column sum): 36
