Grokking the Coding Interview Patterns in Go

Diameter of Binary Tree

Explore how to calculate the diameter of a binary tree by applying depth-first search techniques. Understand the concept of longest path between any two nodes, practice coding the solution in Go, and prepare effectively for tree-related interview questions.

We'll cover the following...

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
