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.

Solved by figuring out a function analagous to the encoder function and then "reversing" the input and output for each position in the overall string using dictionaries, but I saw some people were able to obtain the encoder function and I can't deduce why my encoder function also works, and also why other people's different decoder functions work? Can someone help me understand?
Is anyone willing to explain or help me understand this code a little? I'm pretty lost
My (python) solution works on about 100-200 test cases but fails the rest. When I take an example failed test and put try it on my IDE, it works. Anyone know why this might be the case?
