Solution: Longest Cycle in a Graph

Explore techniques to identify and measure the longest cycle in a directed graph with nodes having at most one outgoing edge. Understand how to traverse the graph efficiently to detect cycles, track node visitation times, and compute the maximum cycle length. This lesson enables you to implement a solution with linear time complexity and apply it effectively in coding interviews.

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]. ...
