Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    
    int current_window_sum = 0;

    for(int i=0; i< n-k+1; i++){
        for(int j=i; j<i+k; j++){
            current_window_sum += arr[j];
        }
        printf("%d ", current_window_sum);
        current_window_sum=0;
    }

    
}

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;
}
