Solution: Detect Cycle in a Directed Graph
Explore how to identify cycles in directed graphs using a depth-first search method. Understand the use of recursion stacks and visited nodes to detect cycles efficiently. This lesson helps you implement cycle detection in C#, an essential skill for coding interviews involving graph algorithms.

Statement
Given a directed graph, check whether the graph contains a cycle and return a boolean value accordingly.
A cycle occurs when you can start at one vertex, follow a path through the edges, and return to the starting vertex. This means at least one vertex is visited more than once within the same traversal path.
Note: Edges list is interpreted in the following manner:
edges = [[0, 2, 1], [], [2, 1, 0]]
Interpretation:
