Loading collection data...
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.

Apologies, it helps to read the question! (I thought it seemed a little easy!)
I ma be asking a question which has already been answered but in the description it lists Kata.NextBiggerNumber(2017)==2071. Should the result not be 7210 as this would be the bigger number formed by the same digits?
Please can the details for the c# Kata be updated to reflected the expected method name : IsUpperCase() and not is_uppercase()
