C CODE:

#include<stdio.h>

#include <stdlib.h>

int main()

{

int n,i,j,k;

scanf("%d",&n);

for(i=0;i<n;i=i+2)

{

    k=n*i+1;

    for(j=0;j<n;j++)

    printf("%d ",k+j);

    printf("\n");

}

if(n%2==0)

i=n-1;

else

i=n-2;

while(i>-1)

{

    k=n*i+1;

    for(j=0;j<n;j++)

    printf("%d ",k+j);

    i=i-2;

    printf("\n");
