Solution: Closest Node to Path in Tree

Explore how to find the closest node on a path between two nodes in a tree to a given third node. Learn to perform BFS to determine paths and shortest distances, reconstruct the route, and identify the closest node efficiently. This lesson builds skills in tree traversal and BFS application for coding interviews.

We'll cover the following...

Statement

You are given a positive integer, n, representing the number of nodes in a tree, numbered from 00 to n−1n-1. You are also given a 2D integer array edges of length n−1n-1 ...
