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 a branch before backtracking.

Question: How do I implement BFS in C++?
Answer: BFS can be implemented using a queue data structure to keep track of nodes to visit next, starting from a given source node.
