first i hav taken input of 2d array.........and then sorted them using merge sort..... i know there is a problem in my logic.......but i can't find it......help me find it please.....


#include<stdio.h>

int main()
{
    int n,c,i,j,k,l,num;

    scanf("%d",&n);

    c=n-1;
    int ar[c][c];
    num=1;

    for(i=c;i>=0;i--)
    {
        for(j=0;j<n-i;j++)
        {
            ar[i][j]=num;
            num++;
        }
    }

        for(j=1;j<=c;j++)
        {
            for(i=0;i<n-i;i++)
            {
                ar[i][j]=num;
                num++;
            }
        }

            for(i=0;i<n;i++)
            {
                for(j=0;j<n;j++)
                {
                    printf("%d ",ar[i][j]);
                }
                printf("\n");
            }

            return 0;
}

Hi, First of all, you don't need to sort the array. Read the Question properly, we just need to Reprint the Array in a Different Pattern of Diagnals, which is given in the Sample Output.
