Interview Prompt

Define a function make_counter() with a docstring 'Counter closure; each call bumps the count by 1.' that uses nonlocal to maintain an integer and returns a bump() inner function that increments and returns it. Create c = make_counter() and print c(), c(), c() on separate lines.

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
