int main(void)
{
    int i, j;
    for (i = 1; i <= 9; i ++ )
    {
        for (j = 1; j <= 9; j ++)
        {
            int k = i * j;
            if (k % 10 == 4 || k / 10 == 4)
            {
                printf("   ");
                continue;
            }
            printf("%3d", k);
        }
        putchar('\n');
