👍 The time complexity is O(n) if the tree is balanced and O(log n) if it is balanced.
Since you're doing recursion in add_helper the space complexity is the same as the time.

👍 The time complexity is O(n) (not n^2)
The space complexity is O(log n) if the tree is balanced or O(n) if it's not. The space complexity is basically the height of the tree.
