下载的测试点数据检查后也是正常的

#include<iostream>
using namespace std;
int main()
{
    short n=0;
    short temp=0;
    short mtrx[20000];
    short loop=0;
    cin>>n;
    while(temp<n*n)
    {
        cin>>mtrx[loop];
        temp+=mtrx[loop];
        loop++;
    }
    temp=0;
    loop=1;
    for(short i=0;loop<n;i++)
    {
        for(short j=0;j<mtrx[i];j++)
        {
            if(temp==n) {cout<<endl;temp=0;loop++;}
            cout<<i%2;
            temp++;
        }
    }
    return 0;
}
