Solution: Diameter of Binary Tree
Understand how to calculate the diameter of a binary tree by applying depth-first search techniques. Explore both naive and optimized approaches, analyze time and space complexities, and learn to handle longest paths passing through or excluding the root node. This lesson helps you implement an efficient solution to a common tree problem.
Statement
Given a binary tree, you need to compute the length of the tree’s diameter. The diameter of a binary tree is the length of the longest path between any two nodes in a tree. This path may or may not pass through the root.
Note: The length of the path between two nodes is represented by the number of edges between them.
Constraints:
- The number of nodes in the tree is in the range .
