Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int window_limit = n - k;
    for(int i = 0; i <= window_limit; i++) {
        int window_sum = 0;
        for(int j = i; j < i + k; j++) {
            window_sum += arr[j];
        }
        printf("%d", window_sum);
        if(i < window_limit) {
            printf(" ");
        }
    }
}

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;
}
