Interview Prompt
Implement a `CountUp` iterator over a list of integers `values`, plus a `count_up(values)` driver that constructs one, runs it to completion, and returns everything it yields as a list. Each yielded item is `values[i]` scaled by its position in the list.
Summary
It knows where it stopped last time.
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
