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.
Here's what I'm looking at. http://imgur.com/gallery/jVKsTmm/new
As you can see I didn't modify the array at all before logging it. It's not a huge deal, I can always just skip the kata, I just wanted to help out in case this is, in fact, a broken test.
I think I may have run into a bug in this kata. This is what I get for input and the subsequent failure message.
Arguments: [ 1, 2, 3, 4 ], 2
Expected: [4,5,1,2,3], instead got: [3,4,1,2]
How'd the array get bigger? Am I missing something obvious here? Or is this just a bad unit test?
