Solution: Diameter of Binary Tree
Understand how to calculate the diameter of a binary tree by exploring the longest path between any two nodes. Learn to use a depth-first search method to efficiently find the height of subtrees and update the diameter. This lesson guides you through the algorithm, cases where the path passes through or excludes the root, and explains the time and space complexity involved.
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 .
