How is cycle detection implemented in different programming languages?

Cycle detection is a technique used to determine if a graph contains a cycle. Different programming languages have various libraries and algorithms to implement this. Are you interested in a specific language?

Yes, can you explain it in Python?

In Python, you can use Depth-First Search (DFS) to detect cycles in a directed graph. You can maintain a visited set and a recursion stack to track the nodes. If you revisit a node that's in the recursion stack, a cycle exists.

What about in Java?

In Java, you can also use DFS for cycle detection. You can represent the graph using an adjacency list and use a similar approach with a visited array and a recursion stack to identify cycles.

Are there any built-in functions for this in C++?

C++ doesn't have built-in functions specifically for cycle detection, but you can implement it using DFS or BFS. The Standard Template Library (STL) can help with data structures like vectors and sets.
