What is the complexity of topological sorting?
The time complexity of topological sorting is O(V + E), where V is the number of vertices and E is the number of edges.
Can you explain why it has that complexity?
Sure! The algorithm processes each vertex and edge once, leading to the linear time complexity in terms of the number of vertices and edges.
Are there different algorithms for topological sorting?
Yes, the two most common algorithms are Kahn's algorithm and Depth-First Search (DFS) based approach.
Which one is more efficient?
Both algorithms have the same time complexity, but their efficiency can vary based on the graph's structure and implementation.
Can topological sorting be applied to all graphs?
No, topological sorting can only be applied to Directed Acyclic Graphs (DAGs). If there's a cycle, sorting isn't possible.
