#include<bits/stdc++.h>
using namespace std;

// void rev(long int *a,long int n){

// }
// }

int main() {
int t;
cin>>t;
while(t–){
int n;
cin>>n;
int a[n];
for(int i=0;i<n;i++){
cin>>a[i];
}
// rev(a,n);
// for(int i=n-1;i>=0;i–){
// cout<<a[i];
// }
reverse(a,a+n);
for(int i=0;i<n;i++){
cout<<a[i];
}
}

return 0;

}

isn’t this also the correct approach of the problem.
