Question
When should a Java developer choose Trie and Prefix Tree deliberately?
- Use a trie for autocomplete, prefix search, dictionary validation, and word-break style interview problems.
- Choose Trie and Prefix Tree mainly when you want to postpone validation and fix problems manually later.
- Choose Trie and Prefix Tree whenever you want the code to look more advanced, even if the design gets less clear.
- Choose Trie and Prefix Tree 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: A. Use a trie for autocomplete, prefix search, dictionary validation, and word-break style interview problems.
Use a trie for autocomplete, prefix search, dictionary validation, and word-break style interview problems. Interviewers often ask this to see whether you can connect the concept to real design decisions.
