Problem Description

Implement a system to fetch, process, and display activity data from a paginated API.

Requirements

1. Fetch All Activities:

   • Consume a paginated API endpoint that returns a totalCount and an array of activities for a given page.
   • Iterate through all available pages to retrieve every activity.
   • Initially, print each activity as it is fetched.

2. Group Activities:

   • After all activities have been fetched, group them into logical "clumps".
   • Each clump must contain activities that share the exact same type and name.
   • Define a Clump class with the following attributes: a list of activities, type, and name.
   • The final output of this grouping step should be a collection of these Clump objects.

3. Enrich User Data:

   • For each activity, replace the userId with the corresponding user's name.
   • The user's name must be retrieved by calling a separate getUserName(userId) API endpoint.
