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.

It often does. Now that I retried the solution, it failed the first time, and passed the second time in 11.5 seconds. More optimized solutions pass in around 7-9 seconds.
This kind of micro-optimization katas are somewhat problematic on CW, as fluctuations in CW performance can make existing katas either too easy or outright impossible.
