Solution: Longest Path With Different Adjacent Characters

Explore how to calculate the longest path in a tree where adjacent nodes have different characters. Understand the use of topological sorting, in-degree calculation, and chain tracking to solve this problem efficiently. This lesson teaches you to apply these concepts to manage dependencies and optimize tree traversal algorithms in coding interviews.

Statement

You are given a rooted tree with nn nodes, numbered from 00 to n1n - 1, where the tree is connected, undirected, and has no cycles. The tree is represented by a 0-indexed array parent of size nn, where parent[i] is the parent of node ...
