Challenge: Detect Cycle in a Directed Graph
Explore how to detect cycles in directed graphs by checking for revisits of vertices during traversal. This lesson helps you understand cycle detection logic, enabling you to implement solutions that identify cycles, a key concept in graph theory and coding interviews.

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:
