Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int *temp = arr;
    temp[0]=arr[0];
    int sum=arr[0];
    for(int i=1;i<n;i++)
    {
        sum+=arr[i];
        temp[i]=sum;
    }
    int index_traversal=0;
    while(index_traversal<k-1)
    {
        index_traversal++;
    }
    printf("%d ",temp[index_traversal]);
    int need_to_subtract=0;
    index_traversal++;
    while(index_traversal<n)
    {
       
        int ans=temp[index_traversal]-temp[need_to_subtract];
        printf("%d ",ans);
         index_traversal++;
        need_to_subtract++;
    }
}

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;
}
