Sliding Window Sum

Code

#include <stdio.h>

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

    for(int i = 0;i<=n-k;i++){

        for(int j = i;j<i+k;j++){

            sum += arr[j];

        }

        
        printf("%d ",sum);
        sum = 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;
}
