Interview Prompt
A survey gives you the `heights` of a row of vertical walls. Any two walls, together with the ground between them, form a container whose capacity is the height of the shorter wall times the distance between the two. Return the greatest capacity any pair of walls can hold.
Summary
Two walls, one sky, and a very important question.
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
