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 improve my understanding of graph traversal algorithms?
Answer: Regular practice of MCQs and solving objective questions related to graph traversal will enhance your understanding and retention of key concepts.
