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 arbitrary other characters, return whether every bracket is closed by the correct type and in the right nesting order. Treat any non-bracket character as filler, and treat an empty string as balanced.
Summary
Every opener is a promise. The order you close them in decides whether it holds.
