My issue

I don’t know what is wrong with my code

My code

#include <iostream>
#include <vector>
using namespace std;

int main() {
	int t; cin >> t;
	while(t--){
	    int n; cin >> n;
	    int g = 0;
	    for(int i = 0; i < 7; i++){
	        int a;
	        cin >> a;
	        if(a > g){
	            g = a;
	        }
	    }
	    for(int i = 7; i < n; i++){
	        int a; 
	        cin >> a;
	    }
	    cout << g << endl;
	    
	}
	return 0;
}

include
using namespace std;

int main() {
// your code goes here
int t;
cin>>t;
while(t–){
int n,c=0,ans;
cin>>n;
int A[n], B[7]={0};
for(int I=0;I<n;I++)cin>>A[I];
for(int I=0;I<n;I++){
B[A[I]%7]++;
if(A[I]<=7)c++;
if(c==7){
ans=I+1;
break;}
}
cout<<ans<<endl;
}
return 0;
}
