FAQs

Question: What is the main difference between BFS and DFS?
Answer: BFS explores all neighbors at the present depth prior to moving on to nodes at the next depth level, while DFS explores as far as possible along each branch before backtracking.

Question: How can I implement BFS in C++?
Answer: BFS can be implemented using a queue data structure to keep track of nodes to be explored, ensuring that nodes are processed in the order they are discovered.
