Solution: Longest Cycle in a Graph
Explore how to identify and calculate the longest cycle in a directed graph where each node has at most one outgoing edge. Understand an iterative traversal method that tracks node visits and detects cycles, enabling you to solve this problem optimally with O(n) time and space complexity.

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]. ...
