Solution: Detect Cycle in a Directed Graph

Explore how to detect cycles in directed graphs using depth-first search traversal in JavaScript. Understand the process of tracking visited nodes and recursion stacks to identify cycles, and learn the algorithm's implementation and complexity to enhance your problem-solving skills for coding interviews.

We'll cover the following...

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:

0:0,2,10: 0, 2, 1 ...
