Solution: Detect Cycle in a Directed Graph
Explore how to detect cycles in directed graphs by applying depth-first search (DFS) traversal. This lesson helps you understand the recursive approach, track visited nodes, and identify cycles efficiently, preparing you to implement graph algorithms confidently in JavaScript.

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:
None
