BST Height Formula:
From: | To: |
The height of a binary search tree is the number of edges on the longest path from the root node to a leaf node. It's a fundamental measure of a tree's structure and affects search time complexity.
The calculator uses the BST height formula:
Where:
Explanation: The height of a tree is determined by its tallest subtree plus one for the current node.
Details: Tree height directly impacts search efficiency (O(h) time complexity). Balanced trees (minimum height) provide optimal performance.
Tips: Enter the heights of left and right subtrees (0 if subtree is empty). The calculator will compute the total height of the BST.
Q1: What's the height of an empty tree?
A: The height of an empty tree (null node) is typically considered -1 or 0, depending on definition.
Q2: How does height relate to balance factor?
A: Balance factor is the difference between left and right subtree heights. AVL trees maintain |balance| ≤ 1.
Q3: What's the minimum height of a BST with n nodes?
A: Minimum height is ⌊log₂n⌋, achieved by a complete binary tree.
Q4: What's the worst-case height?
A: Worst-case height is n-1 (degenerate tree where each node has only one child).
Q5: How is height used in tree rotations?
A: Rotation operations maintain/restore balance by reducing overall tree height.
