You are designing a module that handles login and security for an application. The basic functions of the class are:

a. The user must first enter a valid login name. The system checks to see that the name is valid before asking for a password. If it is not valid, the user can either exit (cancel) or re-enter the name.
b. The user then must enter the password associated with the name. The system validates that the password is the appropriate one for the login name. If the password is invalid, the user can cancel and exit, re-enter the password, or go back to step (a) and re-enter the login name.
c. The user selects a function. The system validates that the function is one that the user is allowed to do. If not, the user can exit, re-enter the function, or go back to step (a) and start the process over again.

Create a state diagram that describes the above actions. Ensure that you name each state and include triggers that cause the transitions as well as any conditions that may apply.
