简单的考察输入输出的题。

#include <iostream>
#include <cstdio>
#include <cstdlib>
#include <cstring>
using namespace std;


int main()
{
    //freopen("D:\\t.txt", "r", stdin);
    int n, s;
    scanf("%d%d", &n, &s);
    s--;
    for (int i = 1; i <= n; i++)
    {
        s += i;
        int p = (s - 1) % 9;
        if (i != 1)
            for (int j = 0; j < (i - 1) * 2; j++)
                printf(" ");
        printf("%d", p + 1);
        for (int j = i; j < n; j++)
        {
            p = (p + j) % 9;
            printf(" %d", p + 1);
        }
        printf("\n");
    }
}
