  2. There is no practical difference in behavior, performance, or maintainability when Counter and Frequency Maps is involved.
  3. The oldest option related to Counter and Frequency Maps is always the right production choice regardless of workload or context.
  4. Differences around Counter and Frequency Maps 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
