Question
When should a Java developer choose Depth-First Search deliberately?
- Choose Depth-First Search mainly when you want to postpone validation and fix problems manually later.
- Choose Depth-First Search whenever you want the code to look more advanced, even if the design gets less clear.
- Choose Depth-First Search only to avoid modeling domain rules explicitly in Java code.
- Use DFS for connected components, topological reasoning, path existence, and tree or graph backtracking problems.
Hint
Think about the production scenario where the choice genuinely improves the code.
Answer and rationale
Correct answer: D. Use DFS for connected components, topological reasoning, path existence, and tree or graph backtracking problems.
Use DFS for connected components, topological reasoning, path existence, and tree or graph backtracking problems. Interviewers often ask this to see whether you can connect the concept to real design decisions.
