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.

Oh, I think that the description is misleading. It says that "The occurence of two or more equal words next after each other count as one.", which I think that means that "dog dog dog dog" should count as 1, although the title of the kata is not consistent with that. Anyway, I've realized that my solution has the same issue :_)
Would this work with 4 consecutives appearances of a word?
