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.

A word can have a single letter, and if a string is not empty it has 0-index char anyway; so this error may occure only if a word is empty string. But how is it possible if code passes all tests, meaning that a given argument is always a valid phrase? maybe an iterpreter issue..

It's a very straightforward solution, but what if string would be really long? Will have to wait a lot.
