Dynamic Sensor Buffer

#include <iostream>

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

    if (n < 1) {
        return 0;
    }

    int* a = new int[n];
    int sum = 0;
    for (int i = 0; i < n; ++i){
        std::cin >> a[i];
        sum += a[i];
    }
    std::cout << sum/n;

    delete[] a;

    // Write your dynamic buffer allocation code here

    return 0;
}
