Solution: Detect Cycle in a Directed Graph
Explore how to detect cycles in a directed graph using a depth-first search approach. This lesson guides you through the algorithm implementation in Java, explains the use of recursion stacks and visited nodes, and covers time and space complexity for an efficient graph traversal.

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
