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.
'5' is not an alphabetical character, it is an alphanumeric character. The instructions explicitly state that only alphabetical characters should be considered part of "words" so the output expected should be "d3y sat".
Ah! I see why it is still part of it now. The instructions seemed contradictory but I get how it all works now... now that I have code that perfectly eliminates all of them. XD
This kata was great! I hit the reset button after 4.5 hours of the pain of making the wrong code work flawlessly (LOL!) and got it within 45 minutes. I need to learn how to remember what I'm doing better! XD
The brackets you see is the way how JUnit formats the value in attempt to show the difference between actual and expected values. Tests do not expect these brackets to occur in the returned value, it's just how the value is formatted by JUnit assertion method.
