Interview Prompt
Implement a permission tracker. The function receives a list of operations, each a 2-element list [op, permission] where op is 'add', 'remove', or 'check'. For each 'check' operation, append True or False (whether the permission is currently granted). Add and remove operations produce no output. Return the list of check results in order.
Summary
Every door has a guest list.
