My Problem

I can’t AC this problem, im using a brute force methode, but it just doesnt work for some reason. Someone please help me!

My Code

#include <iostream>
using namespace std;
int p[105];
int main()
{
    int n;
    cin>>n;
    int ans = 0;
    for (int i = 0; i < n; i++)
        cin>>p[i];
    for (int i = 0; i < n; i++)
    {
        for (int j = i+1; j < n; j++)
        {
            int avg = 0;
            for (int k = i; k <= j; k++)
                avg += p[k];
            avg /= j - i;
            for (int k = i; k <= j; k++)
                if (p[k] == avg)
                {
                    ++ans;
                	break;
                }
        }
    }
    cout << ans;
    return 0;
}

I checked the solution, and it was basically the exact same code as me, the only difference was instead of iterating from i+1 to n, it iterated from i to n. They also used doubles for avg variable.

Here is my code after looking at the solution (the AC version):

#include <iostream>
using namespace std;
int p[105];
int main()
{
    int n;
    cin>>n;
    int ans = 0;
    for (int i = 0; i < n; i++)
        cin>>p[i];
    for (int i = 0; i < n; i++)
    {
        for (int j = i; j < n; j++)
        {
            double avg = 0;
            for (int k = i; k <= j; k++)
                avg += p[k];
            avg /= j - i + 1;
            for (int k = i; k <= j; k++)
                if (p[k] == avg)
                {
                    ++ans;
                	break;
                }
        }
    }
    cout << ans;
    return 0;
}
