Solution: Longest Cycle in a Graph

Explore how to solve the problem of finding the longest cycle in a directed graph with nodes having at most one outgoing edge. Learn to use traversal techniques and visit tracking to detect cycles and calculate their lengths efficiently, ensuring you understand time and space complexity considerations.

Statement

You are given a directed graph with n nodes, labeled from 0 to n - 1. Each node in the graph has at most one outgoing edge.

The graph is described using a 0-indexed integer array edges of length n, where:

  • edges[i] represents a directed edge from node i to node edges[i]. ...
