Sliding Window Sum

Code

#include <stdio.h>

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

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;
}
