definetly not lol

Please don't post solutions in Discourse. It means you can make changes (if you want) to your code before submitting it. After that, that's the solution it'll show no matter how many times you submit another version. Note this kata is a Draft, so you can't submit your solution.

Probably forgot to delete it

My explanation wasn't very good, but when the Kata says it wants the "the number of times where two integers in the array have a difference of n" it is ignoring the sign of the difference. Appreciate this could be clearer, but this can be inferred from the test cases.
