Question

In Java, which comparison about Linked List Reversal is accurate?

  1. There is no practical difference in behavior, performance, or API design when Linked List Reversal is involved.
  2. An iterative reversal uses constant extra space, while a recursive reversal uses the call stack to defer rewiring.
  3. The oldest option related to Linked List Reversal is always the right production choice regardless of context.
  4. Differences around Linked List Reversal 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: B. An iterative reversal uses constant extra space, while a recursive reversal uses the call stack to defer rewiring.

An iterative reversal uses constant extra space, while a recursive reversal uses the call stack to defer rewiring. This is the comparison that usually separates memorization from understanding.
