测试点输出都一样，为什么爆0

#include<bits/stdc++.h>
using namespace std;
int main(){
    int n,a,b[40000];
    cin>>n;
    int s=0,s1=0,s2=0;
    while(s<=n*n){
    cin>>a;
    s+=a;
    s1++;
    for(int j=1;j<=a;j++){
        if(s2==n){
            cout<<endl;
            s2=0;
        }
        if(s1%2==1){
            cout<<'0';
        }
        else cout<<'1';
        s2++;
        }   
    }

}```

第七行应该是s<n*n

#include<bits/stdc++.h>
using namespace std;
int main(){
    int n,a,b[40000];
    cin>>n;
    int s=0,s1=0,s2=0;
    while(s<n*n){
    cin>>a;
    s+=a;
    s1++;
    for(int j=1;j<=a;j++){
        if(s2==n){
            cout<<endl;
            s2=0;
        }
        if(s1%2==1){
            cout<<'0';
        }
        else cout<<'1';
        s2++;
        }   
    }

}
