Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int i=0;
    while(i<n-k+1) {
        int sum =0;
        for(int j =i;j<k+i;j++){
            sum+= arr[j];

        }
        i++;
        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;
}
