Solution: Diameter of Binary Tree
Explore how to compute the diameter of a binary tree by using a depth-first search approach. Understand two key scenarios where the longest path may or may not pass through the root. This lesson guides you through optimizing the solution with recursive traversal and calculating subtree heights to determine the maximum diameter, improving your problem-solving skills with trees in coding interviews.
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 .
