This is a USE CASE from a communication-based messaging web application: Use case: Create Account: People create an account by entering their email address, a username, and a password. Per email address, they are only permitted to create one account. Because usernames are also distinctive, no two users can share the same username even if their accounts are linked to various email addresses. Question: Create two component diagrams for the use case (Create Account) above using Model-View-Controller architecture style and PublishSubscriber architecture styles. Create the diagrams using proper software and don't make it by hand
