My issue

Is it wrong?

please, i need justification?

include
using namespace std;

int main() {
// your code goes here
int t;
cin>>t;

while(t--) {
    int n;
    cin>>n;
    string s;
    cin>>s;
    
    for(int i=0;i<n;++i) {
        if(s[i]=='1') {
            for(int j=i+1;j<n;++j) {
                s[j]='0';
            }
            break;
        }
    }
   
    
    cout<<s<<"\n";
}

return 0;

}

My code

#include <iostream>
using namespace std;

int main() {
	// your code goes here
	int t;
	cin>>t;
	
	while(t--) {
	    int n;
	    cin>>n;
	    string s;
	    cin>>s;
	    
	    for(int i=0;i<n;++i) {
	        if(s[i]=='1') {
	            for(int j=i+1;j<n;++j) {
	                s[j]='0';
	            }
	            break;
	        }
	    }
	   
	    
	    cout<<s<<"\n";
	}
	
	return 0;
}
