Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    for (int i = 0; i<= n - k;i++){
        int sum = 0;

        for (int j = i;j< i +k; j++){
            sum += arr[j];
        }
        printf("%d ", sum);
    }

}

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;
}
