Interview Prompt

A monitoring system needs a stack that retrieves the minimum element in constant time without scanning the whole stack. Implement a stack class with push, pop, and get_min methods, all operating in O(1) time.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your python solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
