Dynamic Sensor Buffer

#include <iostream>

using namespace std ; 

int main() {
    int n;
    std::cin >> n;

    if (n < 1) {
        return 0;
    }

    // Write your dynamic buffer allocation code here

    int* ptr = new int[n] ; 
    int sum = 0 ; 
    for(int i = 0 ; i < n ; i++)
    {
        cin >> ptr[i] ; 
        sum += ptr[i] ; 
    }

    cout << sum / n ; 
    delete[] ptr ; 

    return 0;
}
