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++){
    int sum = 0;
    for (int j = i; j< i+k; j++){
        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;
}
