Consider an online bank website login screen, we have to enter correct customer username and password in the login screen to access his account at first attempt. We allowed 3 attempts, and if users enter the wrong password at 3th attempt, the system closes the application automatically. Each user should have two accounts, checking and saving. If the customer accesses his account successfully, he can view his checking account or savings account by clicking a corresponding button, there is one button for each account type. For example, if the customer clicked on a checking account button, details of his checking account will be displayed.

The customer can move from checking account to the savings account and from saving account to checking account by a specific button. Also, the customer can sign out from his account at any time if he clicks a sign-out button.

1. Draw the state transition diagram for this application.
2. Derive the State Transition table from the state transition diagram.
