@Offending_username 拿到10分，代码：

#include <iostream>
#include <cstring>
using namespace std;
int a[40010], n, zt, iindex, m;
int main() {
    cin >> n;
    memset(a, 0, sizeof(a));
    while(1) {
        cin >> m;
        for(int i = 1; i <= m; i++) a[i] = zt;
        zt = !zt, iindex += m;
        if(iindex = n * n) break;
    }
    for(int i = 1; i <= n; i++)
    {
        for(int j = 1; j <= n; j++) cout << a[j + (i - 1) * n];
        cout << endl;
    }
    return 0;
}

@Zhuyiming0325 zt=!zt有风险，有可能会给你蹦出来一个奇奇怪怪的非0数

没有吧

@Offending_username 是的不会

by Offending_user_name_ @ 2023-01-27 14:36:55

@Zhuyiming0325 第12行和10行有问题，其实都是小问题。

你刚AC的 @Offending_username

by Offending_user_name_ @ 2023-01-27 14:41:31

@Zhuyiming0325 没错，在你原来的代码上改了4处错误就对了。
