Also worth noting that when you post this code on the respective kata, use the tilde key (`) three times to start a code block, and another three times at the end. You can optionally include the language used after the first set of tildes to have highlighting enabled. Using code blocks makes it much more readable.

Don't post code here, use that kata discourse and mark your post as having spoiler content.
