Solution: Diameter of Binary Tree

Explore how to compute the diameter of a binary tree by applying depth-first search techniques. Understand how to calculate subtree heights and update the diameter by evaluating paths through nodes. This lesson helps you implement an O(n) time complexity algorithm to solve the problem efficiently.

We'll cover the following...

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 [1,500][1, 500].
  • −100≤-100 \leq
