Interview Prompt
A template engine checks its output by enumerating every legal bracket nesting it could emit. Given a non-negative integer `n`, return every well-formed string built from `n` pairs of parentheses.
Summary
Building balanced brackets is an art form.
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
