Solution: Detect Cycle in a Directed Graph

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:

$0: 0, 2, 1$
