Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    // int left =0;
    // int right = k-1;
    
    for(int i =0; i<=n-k; i++)
    {
        int sum =0;
        int left = i;
        int right = i + (k-1);
        while(left <=right)
        {
            if(left == right)
            {
                sum= sum+arr[left];
            }
            else
            {
                sum = arr[left]+arr[right];
            }
            
            left++; 
            right--;
        }
        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;
}
