1. What is Binary Tree Height?

The height of a binary tree is the number of edges on the longest path from the root node to a leaf node. It's a fundamental property used in analyzing tree structures and algorithms.

2. How Does the Calculator Work?

The calculator uses the binary tree height formula:

Where:

• \( Height(left) \) — Height of left subtree
• \( Height(right) \) — Height of right subtree

Explanation: The height of a tree is determined by the taller of its two subtrees plus one for the current level.

3. Importance of Tree Height Calculation

Details: Tree height is crucial for analyzing algorithm complexity, balancing trees (like AVL trees), and optimizing search operations in binary search trees.

4. Using the Calculator

Tips: Enter the heights of left and right subtrees (0 if subtree is empty). The calculator will compute the total height of the binary tree.

5. Frequently Asked Questions (FAQ)

Q1: What's the height of an empty tree?
A: The height of an empty tree is typically considered -1 or 0, depending on definition. In this calculator, empty subtrees should be entered as 0.

Q2: How does this relate to balanced trees?
A: A tree is balanced if the heights of the two subtrees of every node differ by no more than 1.

Q3: What's the time complexity of height calculation?
A: O(n) when calculated recursively for the entire tree, as it needs to visit every node.

Q4: How is height different from depth?
A: Height is measured from leaf to root (maximum depth), while depth is measured from root to a specific node.

Q5: What's the minimum height of a binary tree with n nodes?
A: Minimum height is ⌊log₂n⌋ for a complete binary tree.
