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.

exact copy of my solution!
It's ok if you want to leave the issue open / re-raise it if you want. Perhaps someone more familiar with Java would know a way to fix it.
Oh, I forgot about that you have to invalidate all current solutions, sorry.
Thanks for reporting. Unfortunately, I'm not sure how I can resolve this issue without invalidating current solutions :/
Excuse me, it's not a big issue, but you have a typo in method's name in Java - longestAlp[h]abeticalSubstring
Who have the longest solution?
Me, of course :(
Following test cases weren't specified in the description:
FixedTest1 and FixedTest2 : exponent is -1 and return value -1
RandomTest : exponent is 0 and return value is -1
Would you like to describe this edge case in kata?
