Sliding Window Sum

Code

#include <stdio.h>

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

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;
}
