Question

In Java, which comparison about Heap Operations and Invariants is accurate?

  1. There is no practical difference in behavior, performance, or API design when Heap Operations and Invariants is involved.
  2. The oldest option related to Heap Operations and Invariants is always the right production choice regardless of context.
  3. Heaps are optimized for repeated best-element access, while sorted arrays optimize full-order traversal and binary search.
  4. Differences around Heap Operations and Invariants are mostly cosmetic, so correctness and maintainability do not change.

Hint

Focus on the behavior or tradeoff, not just the keyword.

Answer and rationale

Correct answer: C. Heaps are optimized for repeated best-element access, while sorted arrays optimize full-order traversal and binary search.

Heaps are optimized for repeated best-element access, while sorted arrays optimize full-order traversal and binary search. This is the comparison that usually separates memorization from understanding.
