What are the differences between DFS and BFS?
DFS (Depth-First Search) explores as far as possible along each branch before backtracking, while BFS (Breadth-First Search) explores all neighbors at the present depth prior to moving on to nodes at the next depth level.
Can you give me an example of when to use each?
Sure! Use DFS when you want to explore all possibilities, like in puzzles or mazes. Use BFS for shortest path problems, like finding the quickest route in a map.
What are the time complexities of both algorithms?
Both DFS and BFS have a time complexity of O(V + E), where V is the number of vertices and E is the number of edges.
Are there any specific data structures used for each?
Yes! DFS typically uses a stack (or recursion), while BFS uses a queue to keep track of the nodes to explore.
