Ok so you're missing some of the methods. The ones you have are working although you have some issues with time/space complexity. We'll go over things in class today. Let me know if you have questions.

s.slice creates a new array and copies all the individual elements over and so is O(n) by itself.

👍
This works, but because you create a new array with each recursive call this is O(n2) for both time/space complexity.
