You should say which language you're using. You probably misunderstand something and need to analyze it better. See if this can help: https://docs.codewars.com/training/troubleshooting. If you do think there's a problem or something impossible to understand, you may post your code with a spoiler flag, and clear examples of logs/test cases.
