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.
Get started now by creating a new collection.
Well the assertion messages of Python test framework are suboptimal.
the issue here is probably not about whether their solution is correct, but that the test output itself can (if misreading, but reasonably so) seem to contradict the instructions (as it may seem to claim that 'TTTTUUUUU' was the input)
..which I agree with. this is poor wording which assumes a different context for the solver than the solver is actually in
Your algorithm is not correct. You append an 'U' for every 'T' (not exactly, actually it's even weirder but you get the point).
Not a kata issue.
