Sample Output

Explanation

Computes sum using pointer arithmetic inside a function.

Starter Code

#include <stdio.h>

long long sumArray(int *ptr, int n) {
    // Write your code here
}

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        int arr[n];
        for (int i = 0; i < n; i++) scanf("%d", &arr[i]);
        printf("%lldn", sumArray(arr, n));
    }
    return 0;
}
