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.

It seems you're mutating the input and that generates the wrong expected answer. Modify your code to not mutate the input and try again.
Please check the code testing, I had an entry: [97, 75] and I received this error:
"Expected: '[97,97], instead got: '[75,97]' "
, my code's output should be accepted.
