Well done Beatrice, you hit the learning goals here. Nice work. I had a few comments on time/space complexities, but otherwise very well done. Let me know if you have any questions.

👍 The time & space complexities are both O(log n) if the tree is balanced and O(n) if unbalanced.

👍 The time complexity here is right, but the space complexity is O(log n) if the tree is balanced and O(n) if it's not.
