Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    
    for(int i = 0;i<= n-k  ;i++){
        //first for loop determines total output lenght
        int sum = 0;
        for(int j = i ;j < (i+k);j++){
            //inner for loop determines the start of window
            sum += arr[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;
}
