An employee submits a leave application stating details such as the dates when the leave is

required and the reason. The application is first reviewed by the employee$$s immediate

manager, who may approve it$,$ reject it$,$ or ask for more clarification. If the manager approves

the application, it goes to the director, who may either approve or reject the application based

on other criteria. The final decision to approve or reject therefore rests with the director. If

the manager rejects the application, it is considered rejected. If the manger asks for

clarification, the employee has to resubmit the application with the clarification. At this stage,

the manager has only two choices $$ approve or reject $($in other words, there is only one

opportunity to submit a clarification$).$ Of course, the employee, at any time, may decide to

withdraw the application, even after it has been approved by the director.

Prepare a state diagram for the leave application, clearly showing the different states and

transitions between them, including the transitions and guard conditions
