Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    int left=0;
    int right=0;
    while(left<=right  && right<n){
        if((right-left)+1<k){
            right++;

        }
        else{
            int sum=0;
            for(int i=left;i<=right;i++){
                sum+=arr[i];

            }
            printf("%d ", sum);
            left++;
            right++;
        }
    }


    // Your logic here
}

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;
}
