Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Nice one, ha!
TIL about repeat method! Thank you:)
I really like this idea of filtering out the negative items first!
Thank you for leaving comments with links! Legend!
Oh my... I feel bad about not thinking of this and implementing my solution in a much more complicated way!
Still an issue!
As per classic convention highest number for this kata should be <3999
Because if you allow entering 4 symbols of the same type, why "4" is not equal to "IIII" ?
