Solution: Diameter of Binary Tree
Explore how to calculate the diameter of a binary tree, defined as the longest path between any two nodes. Understand both naive and optimized depth-first search approaches, learn to assess height and diameter at each node, and improve your grasp of tree traversal and recursion. By the end, you will know how to implement an efficient solution with O(n) time complexity.
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 .
