How can I optimize BFS and DFS algorithms?
To optimize BFS, consider using a queue with a hash set to track visited nodes. For DFS, use iterative deepening.
What are the main differences between BFS and DFS?
BFS explores all neighbors at the present depth before moving on, while DFS goes as deep as possible down one branch before backtracking.
Can you give me an example of when to use BFS over DFS?
Use BFS when you need the shortest path in an unweighted graph, like in social networking applications.
Are there any specific data structures that can help with these optimizations?
Yes, using adjacency lists for graph representation can save space and improve performance for both BFS and DFS.
