Thanks for getting in what you did. Not bad, you had the methods right, just look at my feedback regarding the time/space complexity.

👍 However the space & time complexity are O(n^2) because the slice you do has space/time complexity of O(n)

Also you're using the exact method I told you not to use.

This works, but once again the time complexity is O(n^2)

Chris, I wasn't sure on how to do start the final one, but wanted to get this in. I will try to re-attempt this week. Thanks!
