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.

I did a recursive backtracking solution in python. I had to set the maximum recursion limit to avoid hitting that for the larger test cases. Is there an major optimization I am missing. If there isn't, can we have the test up the recursion limit, which can confuse ppl thinking there solution is invalid.

Got the same bug.
Testing for 'nbK55htf w'
It should work with random inputs too: '-. -... -.- ..... ..... .... - ..-. .--' should equal '-. -... -.- ..... ..... .... - ..-. .--'
