Solution: Longest Cycle in a Graph
Explore how to identify and measure the longest cycle in a directed graph with at most one outgoing edge per node. Learn an efficient traversal technique that tracks visitation order and detects cycles by comparing node visit steps, enabling you to return the longest cycle length or -1 if none exists.

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 nodeito nodeedges[i]. ...
