Your very first task is to create a registration and login feature. This feature needs to allow users to $($Read through the entire task before you start any work$)$:

Create an account by entering username, password, first name and last name.

a$.$ The system needs to check that the following conditions are met, and reply with the appropriate output message:

$\frac{7}{23}$

Login to the account using the same username and password.

a$.$ The system should provide the following messages to verify the user's authentication state:

$\backslash$table$[[$Conditions$,$Messages,$],[,$True,False$],[\backslash$table$[[$The entered$],[$IIcarnam$]],$"Welcome,$]]$
