What is the complexity of topological sorting?

MagicBuddy
MagicBuddy

The time complexity of topological sorting is O(V + E), where V is the number of vertices and E is the number of edges.

😀
You

Can you explain why it has that complexity?

MagicBuddy
MagicBuddy

Sure! The algorithm processes each vertex and edge once, leading to the linear time complexity in terms of the number of vertices and edges.

😀
You

Are there different algorithms for topological sorting?

MagicBuddy
MagicBuddy

Yes, the two most common algorithms are Kahn's algorithm and Depth-First Search (DFS) based approach.

😀
You

Which one is more efficient?

MagicBuddy
MagicBuddy

Both algorithms have the same time complexity, but their efficiency can vary based on the graph's structure and implementation.

😀
You

Can topological sorting be applied to all graphs?

MagicBuddy
MagicBuddy

No, topological sorting can only be applied to Directed Acyclic Graphs (DAGs). If there's a cycle, sorting isn't possible.
