Add User With Active Task Quota | Dataford Interview Questions

Add a user with a quota for active tasks.

Implement add_user(users, user_id, quota). Return False for an existing user or a negative quota; otherwise add the user and return True. The input dictionary uses string user IDs, matching JSON object keys. New users start with zero active tasks.

Constraints

users is a dictionary whose keys are string representations of user IDs.
user_id is an integer.

A quota of zero is valid.
