Dynamic Sensor Buffer

#include <iostream>

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

    if (n < 1) {
        return 0;
    }

    // Write your dynamic buffer allocation code here
    int* arr= new int[n];
    int temp=0;
    for (int i=0;i<n;i++){
           std::cin>>arr[i];
           temp += arr[i];   
    } 
    std::cout<<temp/n;
     delete [] arr;
    return 0;
}
