Challenge: Detect a Cycle in a Graph

Explore how to detect cycles in graphs by understanding the concept of loops in graph traversal. Learn to implement a DetectCycle function that returns true when a cycle exists and false otherwise. This lesson helps you develop problem-solving skills in graph algorithms, focusing on cycle detection with step-by-step algorithm design and coding practice in C#.

Problem statement

The concept of loops or cycles is very common in graph theory. A cycle exists when we traverse the graph and come upon a vertex that has already been ...
