Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int a[], int n, int k) {
    // Your logic here
    int i=0,j=k,sum=0;
    while(j<=n){
        for(int l=i;l<j;l++){
            sum = sum + a[l];
        }
        printf("%d ",sum);
        i++;
        j++;
        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;
}
