Fast recall rules
- If the question is about a value type, check operator return types first.
- If the question is about a branch or loop, track state carefully.
- If the question is about a collection, ask whether order, shape, or mutability matters.
- If the question is about file output, check header handling and type conversion.
- If the question is about recursion, check the base case and the shrink step.
- If the question is about classes, separate class state from instance state.
