Interview Prompt
Each record in `activities` is one email event: a dict with a `user_id` and an `action` that is either `send` or `receive`, and both count toward a user's activity. Rank users by their total activity from most to least, settling ties alphabetically by `user_id`.
Summary
Some inboxes see more action.
