DIY: Diameter of Binary Tree

Understand how to determine the diameter of a binary tree, which is the longest path between any two nodes measured by edges. This lesson guides you through implementing a function to compute the diameter, helping you strengthen tree traversal and recursion skills useful in coding interviews.

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 ...
