Sliding Window Sum

Code

#include <stdio.h>

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

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;
}
