Question
When should a Python developer choose Two-Pointer Technique deliberately?
- Choose Two-Pointer Technique mainly when you want to postpone validation and fix issues manually later.
- Choose Two-Pointer Technique whenever you want the code to look more advanced, even if the design gets less clear.
- Use two pointers for sorted pair problems, in-place compaction, partitioning, and palindrome-style checks.
- Choose Two-Pointer Technique only to avoid modeling the real data shape or domain contract explicitly.
Hint
Think about the production scenario where the choice genuinely improves the code.
Answer and rationale
Correct answer: C. Use two pointers for sorted pair problems, in-place compaction, partitioning, and palindrome-style checks.
Use two pointers for sorted pair problems, in-place compaction, partitioning, and palindrome-style checks. Interviewers often ask this to see whether you can connect the concept to real design decisions.
