Please can you post Kata-specific problems on the discourse page for that Kata instead of the forum which is for general topics. Each Kata has an automatic discourse page in which you can mark your comment as a question, which means it's easier for me to help (since it's easier to find). Also, since this is a forum page, I can't mark your comment as a spoiler, meaning people can look at your code and use it themselves, however on the discourse page I can hide your solution.
