An elevator serves several floors, and `floors` holds the list of stops on each one. Return the full trip: every stop in order going up, then the same stops retraced coming back down.
Summary
Nested floors. One path through.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your Python against test cases
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
