Oh well, I didn't know that the kata was broken, but it was a good opportunity to practice. Thank you very much for your time and advice !! I will try to solve what you said, even if the translation isn't going anywhere. By the way, there is no specific reason for the Boolean thing; I just thought it was better to use it in methods than using the primitive. Anyways, thank you very much for your help, and sorry for not responding until today :).
