Interview Prompt
A config parser has to reject malformed input before it reaches the evaluator. Given a string `s` that mixes the three bracket pairs `()`, `[]`, `{}` with other characters, return whether every bracket is closed by the correct type and in the right nesting order.
Summary
Every opener is a promise. The order you close them in decides whether it holds.
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
