Prompt

Problem: [problem statement with input size limits].
Give 2 approaches: a simple one and an efficient one. For each: idea, pseudocode, time and space complexity, and when it breaks. Then implement the efficient one in [language] with tests for edge cases.

Replace everything in [square brackets] with your own details.

Settings & parameters

DeepThink on

Variations

Interview practice: give hints only.
Optimize for memory instead of speed.

Tips

Input size limits decide the right approach.
Run the tests before trusting the code.
