Question

In Python, which comparison about collections.deque for Stacks and Queues is accurate?

  1. There is no practical difference in behavior, performance, or maintainability when collections.deque for Stacks and Queues is involved.
  2. The oldest option related to collections.deque for Stacks and Queues is always the right production choice regardless of workload or context.
  3. Deque handles both ends efficiently, while a list is stronger for indexed access but weaker for front removals.
  4. Differences around collections.deque for Stacks and Queues are mostly cosmetic, so correctness and debugging quality do not really change.

Hint

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

Answer and rationale

Correct answer: C. Deque handles both ends efficiently, while a list is stronger for indexed access but weaker for front removals.

Deque handles both ends efficiently, while a list is stronger for indexed access but weaker for front removals. This is the comparison that usually separates memorization from understanding.
