That is my code on c++

#include <iostream>
#include <stdio.h>
using namespace std;
int main()
{
    int k, n;
    scanf ("%d %d", &k, &n);
    int *mas = new int [n];

    for (int i = 0; i < n; i++)
        {
            scanf("%d",&mas[i]);
        }

    int sum = 0;
    for (int i = 0 ; i < n ; i++)
    {
        sum+=mas[i] - k;
    }
    delete[]mas;

    if (sum<0)
        {
    sum = 0;
    cout<<sum;
    return 0;
        }

    cout<<sum;

    return 0;
}
