Question
When should a Java developer choose Heap Operations and Invariants deliberately?
- Choose Heap Operations and Invariants mainly when you want to postpone validation and fix problems manually later.
- Choose Heap Operations and Invariants whenever you want the code to look more advanced, even if the design gets less clear.
- Choose Heap Operations and Invariants only to avoid modeling domain rules explicitly in Java code.
- Use a heap when the program repeatedly inserts items and needs the current minimum or maximum more than full sorting.
Hint
Think about the production scenario where the choice genuinely improves the code.
Answer and rationale
Correct answer: D. Use a heap when the program repeatedly inserts items and needs the current minimum or maximum more than full sorting.
Use a heap when the program repeatedly inserts items and needs the current minimum or maximum more than full sorting. Interviewers often ask this to see whether you can connect the concept to real design decisions.
