Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int shift = (n - k), temp = 0;
    for (int i = 0; i < shift + 1; i++)
    {
        for (int j = 0; j < k; j++)
        {
            temp += arr[j + i];
        }
        printf("%d ", temp);
        temp = 0;

    }
}

int main() {
    int n, k, arr[100];
    scanf("%d %d", &n, &k);
    for (int i = 0; i < n; i++) scanf("%d", &arr[i]);

    sliding_window_sum(arr, n, k);
    return 0;
}
