I tried it some times and I think I know how works that. But the code I wrote is incorrect. So I’m confused how should I write code. Can I get any hints?

Hi, Mayu I tried this one some couple of times too and I think that the hint you need is that the function should return an int and not an array 🙂

Thanks for replying! Yes, my code returns int, but it was incorrect. 🤔
