Question
When should a Java developer choose Breadth-First Search deliberately?
- Choose Breadth-First Search mainly when you want to postpone validation and fix problems manually later.
- Choose Breadth-First Search whenever you want the code to look more advanced, even if the design gets less clear.
- Use BFS for shortest-hop problems, level-order traversal, and any state-space search where steps all cost the same.
- Choose Breadth-First Search only to avoid modeling domain rules explicitly in Java code.
Hint
Think about the production scenario where the choice genuinely improves the code.
Answer and rationale
Correct answer: C. Use BFS for shortest-hop problems, level-order traversal, and any state-space search where steps all cost the same.
Use BFS for shortest-hop problems, level-order traversal, and any state-space search where steps all cost the same. Interviewers often ask this to see whether you can connect the concept to real design decisions.
