DIY: Diameter of Binary Tree

Understand how to calculate the diameter of a binary tree by identifying the longest path between any two nodes. This lesson guides you through implementing a Java function that returns the diameter as an integer, helping you apply tree traversal and path length concepts to solve coding interview problems.

Problem 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 ...
