Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
     for(int x=0;x<=n-k;x++)
     {
        int sum = 0;
        for(int y=x;y<x+k;y++)
            sum+=arr[y];
        printf("%d ",sum);
     }
    // 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;
}
