What is the time complexity of Depth-First Search (DFS)?
An example of an AI chatbot conversation about the complexity of Depth-First Search (DFS).
What is the time complexity of Depth-First Search (DFS)?
The time complexity of DFS is O(V + E), where V is the number of vertices and E is the number of edges.
Can you explain why it's O(V + E)?
Sure! DFS visits each vertex once and explores each edge once, leading to the combined complexity.
How does DFS compare to Breadth-First Search (BFS) in terms of complexity?
Both DFS and BFS have a time complexity of O(V + E), but they differ in their traversal methods.
Are there any space complexity considerations for DFS?
Yes, the space complexity of DFS can be O(V) in the worst case, depending on the implementation and recursion depth.
