Question

Which practice avoids a common mistake with Linked Lists?

  1. Ignore the Linked Lists issue and rely on team discipline instead of clearer APIs or invariants.
  2. Silence the Linked Lists problem by using broad catches, hidden globals, or extra shared mutable state.
  3. Do not overstate linked lists as automatically faster overall when traversal and object overhead still matter.
  4. Prefer the version of Linked Lists that makes behavior less predictable as long as the code still runs.

Hint

Look for the option that protects correctness instead of hiding the problem.

Answer and rationale

Correct answer: C. Do not overstate linked lists as automatically faster overall when traversal and object overhead still matter.

Do not overstate linked lists as automatically faster overall when traversal and object overhead still matter. This is a common failure mode in real Python code and a frequent interview follow-up.
