Question

Which statement about Top-K with a Heap is the strongest interview answer?

  1. Top-K with a Heap is mostly a naming style choice and has little effect on runtime or design.
  2. Top-K with a Heap exists mainly to reduce the number of Java files in a project.
  3. A bounded heap can keep only the k best candidates seen so far instead of storing all values.
  4. Top-K with a Heap matters only for frontend frameworks, not for core Java applications.

Hint

Start with the core rule behind Top-K with a Heap.

Answer and rationale

Correct answer: C. A bounded heap can keep only the k best candidates seen so far instead of storing all values.
