Solution: Longest Cycle in a Graph

Discover how to identify and measure the longest cycle in a directed graph with at most one outgoing edge per node. Explore a traversal-based approach that tracks visit order to detect cycles and calculate their lengths efficiently while understanding 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]. ...
