Solution: Longest Path With Different Adjacent Characters

Explore how to solve the problem of finding the longest path in a rooted tree where consecutive nodes have different characters. Understand the use of topological sorting, managing in-degrees, and combining chains from child nodes to determine the optimal path length efficiently.

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 ...
