Sliding Window Sum

Code

#include <stdio.h>

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

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;
}
