Interview Prompt
A venue's door system reads a stream of access operations in order, where each one grants a guest entry, revokes it, or checks whether a named guest is allowed in at that moment. Given the operations as `[action, name]` pairs with `action` one of `grant`, `revoke`, or `check`, return the result of every `check` in order.
Summary
Every door has a guest list.
