Codding challenge: social media API

Hello, this challenge consists on creating an API that keeps track of your social media accounts and displays your followers, who you follow. It doesn't end here, if you unfollow someone or if someone unfollows you, it will display who unfollowed (or who you unfollowed) as well as with the new updated lists.

The issue does not identify repository files, tests, or entry points to read. Clarify the API scope and acceptance criteria first, including how follower lists and unfollow history should be represented; completion would require an agreed design covering those behaviors.
