Solution: Diameter of Binary Tree
Explore how to calculate the diameter of a binary tree by applying depth-first search techniques. Learn to evaluate longest paths that may pass through the root or lie in subtrees, understand the recursive process, and optimize solution efficiency with O(n) time complexity. This lesson helps you implement and analyze an efficient algorithm to solve the binary tree diameter problem effectively.
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 .
