Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int left = 0, right = k - 1;
    int sum = 0;

    while (right < n){
        for (int i = left; i <= right; i++){
            sum += arr[i];
        }
        printf("%d ",sum);
        sum = 0;
        left++; 
        right++;
    }

    return;
}

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;
}
