PRINT THE BOUNDARY VALUES OF AN ARRAY

Consider the following I/O samples.

SAMPLE INPUT :      3

                                  4 7 9
                                  3 6 2
                                  0 4 1

SAMPLE OUTPUT: Upper Boundary : 4 7

                                 Lower Boundary : 0 1

                                 Left Boundary : 4 0

                                 Right Boundary : 9 1

 

C PROGRAM:

#include <stdio.h>
int main()

{

    int n,m,i,j,arr[100][100];

    scanf("%d %d",&n,&m);

    for(i=0;i<n;i++)

    {

        for(j=0;j<m;j++)

        {

            scanf("%d",&arr[i][j]);

        }

    }

            printf("\n");

printf("Upper Boundary : %d %d\n",arr[0][0],arr[0][m-1]);

printf("Lower Boundary : %d %d\n",arr[n-1][0],arr[n-1][m-1]);

printf("Left Boundary : %d %d\n",arr[0][0],arr[n-1][0]);

printf("Right Boundary : %d %d\n",arr[0][m-1],arr[n-1][m-1]);

return 0;

}

 

OUTPUT:
