What are the differences between Kahn's algorithm and Depth-First Search?
Kahn's algorithm is used for topological sorting in directed acyclic graphs, while Depth-First Search (DFS) is a traversal method.
Can you explain how Kahn's algorithm works?
Sure! Kahn's algorithm repeatedly removes nodes with no incoming edges and adds them to the sorted list, updating the graph.
What about the time complexity of both algorithms?
Kahn's algorithm has a time complexity of O(V + E), and DFS also has a time complexity of O(V + E), where V is vertices and E is edges.
In what scenarios would you prefer Kahn's algorithm over DFS?
Kahn's algorithm is preferred when you need a topological sort, especially in scheduling tasks with dependencies.
