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 = left + (k - 1);
    
    // Loop through window od size k 
    for(int i=0;i<=(n-k);i++){
        int sum = 0;

        // get sum of window
        for(int j=0; j<k; j++){
            sum += arr[i+j];
        }
        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;
}
