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.

Duplicate issue.
That's a bug, look at the whacky way they calculate the index.
Description needs to say -1 is expected for case of empty array
Need real tests. Bug-fixing concept is OK for me.
Maybe (s)he wanted to do a bug fixing kata? I meant the part of the initial code.
Random Tests
[]
Should work for random tests! - Expected: -2, instead got: -1
If the array is empty, it should return -1
Random Tests
Log
[ 93, 681 ]
Should work for random tests! - Expected: 0, instead got: 1
681 > 93. Index should be 1, not 0.
Reference solution is wrong. It totally omits the last element.
Also, what's with the whole deal with the initial code with seemingly no purposes and the poorly written tests?
