    scanf("%d",&n);
    space = n-1;
    for ( d=1 ; d <= n ; d++ )
    {
        num = d;
        for ( c = 1 ; c <= space ; c++ )
            printf(" ");
        space--;
        for ( c = 1 ; c <= d ; c++ )
        {
            printf("%d", num);
            num++;
        }
        num--;
        num--;
        for ( c = 1 ; c < d ; c++)
        {
            printf("%d", num);
            num--;
        }
