Solution: Closest Node to Path in Tree

Understand how to identify the closest node to a path between two nodes in a tree by applying breadth-first search twice. This lesson guides you through building adjacency lists, reconstructing paths, and evaluating node distances to solve queries efficiently.

Statement

You are given a positive integer, n, representing the number of nodes in a tree, numbered from 00 to n1n-1. You are also given a 2D integer array edges of length n1n-1 ...
