Interview Prompt
A config parser needs to reject malformed input before it reaches the evaluator. Given a string `s` that mixes the three bracket pairs `()`, `[]`, and `{}` 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.
