Answer 1

#include <stdio.h>


int main()
{
    printf("N = ");
    int N;
    scanf("%d", &N);


    int i;
    printf("\n");
    for(i = 1; i <= N; i++)
        printf("%d ", i);


    printf("\n");


    int j = 1;
    int k = 0;
    for(i = N+1; i <= 2*(N - 1); i++)
    {
        printf("%d ", 4*(N-1)-k);
        k++;
        for(j = 1; j < N; j++)
        {
            printf(" ");
        }
        printf("%d\n", i);
    }
    if(N > 1)
    {
        for(i = 3*N - 2; i >= 2*N - 1; i--)
        {
            printf("%d ", i);
        }
    }




    printf("\n");


    return 0;
}
