13. Above Average C++

#include <iostream>
#include <vector>
int main()
{
    using namespace std;

    int lenght;
    cin >> lenght;
    vector<int> arr;
    int n, sum = 0;
    for (int i = 0; i < lenght; ++i)
    {
        cin >> n;
        arr.push_back(n);
        sum += n;
    }

    // int?!? are you kidding me???
    int average = sum / lenght;

    for (int i = 0; i < lenght; ++i)
        if (arr[i] >= average)
            cout << arr[i] << ' ';

    return 0;
