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.

I'll check that again. Thanks.
Maybe your solution is generated by starting with the second character instead of the first character or something?
I've got all the correct key. Well, but in wrong order.
e.g. my key is "CG" but the solution is "GC" :(
Any idea with that case?
Love this kata. Simple math and simple to implement, yet hard to get the idea.
I insist all of you going to try this kata to read the descripion very carefully.
I missed the 'All of the ?s in an expression will represent the same digit (0-9), and it won't be one of the other given digits in the expression.' part. Be careful. Have fun!
