Nice work Alice, well done. You hit the learning goals here. I had some comments on time/space complexity. However this is well done.

👍 The time complexity is O(log n) if the tree is balanced and O(n) if it's unbalanced.

The space complexity is the same (because of the recursion).

👍 The space complexity (due to recursion) is O(log n) if the tree is balanced and O(n) if it's unbalanced.
