Hello, Iā€™m trying to understand why this solution is returning a wrong answer.

Any feedback would be greatly appreciated :slight_smile:

One thing to note is the question is to find the maximum area of one rectangle. I was taking the maximum possible area of all the rectangles (i.e summing all the areas ).
for example the test case :
8
1 1 1 1 1 1 1 1
output should be 1 not 2 :slight_smile:

This is my implementation. How is it?
#include<bits/stdc++.h>
using namespace std;

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];
    }

    sort(a,a+n);
    int ans=-1;
    int p=1,cnt=0;
    for(int i=n-1;i>=0;i--)
    {
        if(cnt==2)
        {
            break;
        }

        if(a[i]==a[i-1])
        {
            p=p*a[i];
            i--;
            cnt++;
        }
    }

    if(cnt==2)
    {
        cout<<p<<endl;
    }
    else
        cout<<ans<<endl;
}
return 0;

}
