Cheffina comes and asks the chef one puzzle to the chef as, how many squares can be formed in this pattern with all sides of new square are parallel to the original edges of the plate.

# Program:

```
#include <bits/stdc++.h>
using namespace std;
#define ll long long
int main()
{
ios_base::sync_with_stdio(false), cin.tie(NULL);
ll t;
cin >> t;
while (t--) {
ll n;
cin >> n;
ll ans = n * (n + 1);
ans = ans * (2 * n + 1);
ans /= 6;
cout << ans << '\n';
}
return 0;
}
