Sliding Window Sum

Code

#include <stdio.h>

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