Sliding Window Sum

Code

#include <stdio.h>

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

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;
}
