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.
Get started now by creating a new collection.
This is a good kata, I had to try several approaches before I got it to complete within the allotted time. It exposes that I should pay more attention to efficiency than I normally do. Thanks!
The expected/received values on test failures seem to be reversed. I noticed it on Name and LastLogon tests for sure.
I did not know you could slice with a negative index to offset from the end, but now I do, thanks!
That was... more complicated than I anticipated :)
Excellent kata, I don't think I've ever even considered overriding the valueOf method before.
Argh, I should have thought of that!
Good kata, it plays nicely and builds upon the solutions to the "Name Your Space" kata:
