What is the space complexity of a binary tree?
The space complexity of a binary tree is O(h), where h is the height of the tree.
Can you explain why it's O(h)? I thought it would be O(n) for all nodes.
Good question! O(n) is the space complexity for storing all nodes, but O(h) refers to the space used by recursive calls in depth-first traversal.
So, in a balanced binary tree, the height is log(n), right?
Exactly! In a balanced binary tree, the height is log(n), making the space complexity O(log n) for recursive calls.
What about a skewed binary tree?
In a skewed binary tree, the height is n, so the space complexity for recursive calls would be O(n).
