Thanks, I would have fixed these ideas but I was a bit busy and now its retired, I appreciate the time you took to give me some useful tips and Ill take these on board next time. Previous kata I have created have all been very quickly removed with many stating that "It didn't use the correct framework" including FArekkusu. I know it is alot to ask but would it be possible for you to show me how to fix issues such as "user can modify the input" and "sample tests are missing related imports" and how to use the new framework because I really would like a published kata but I am stuck on how to fix these recurring issues.
