Sliding Window Sum

Code

#include <stdio.h>

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