Academic Dishonesty:

Your task is to simulate of college and classrooms: There are four kinds of threads: students, visitors, monitor and a one Lecturer per classroom. students must wait to enter the classroom if a class is running, enter, and then sitDown. At some point, the Lecturer enters the classroom. When the Lecturer is in the classroom, no one may enter, and the students may not leave. visitors may leave. Once all students check-in, the Lecturer can StartLecture. After some time, the Lecturer leaves and all students can leave.
 
To make these requirements more specific, let’s give the threads some functions to execute, and put constraints on those functions. 
• students must invoke enter, sitDown, and leave. 
• The Lecturer invokes enter, smart lecture and leave. 
• visitors invoke enter, sitDown and leave. 
• While the Lecturer is in the classroom, no one may enter and students may not leave. 
• The Lecturer cannot start lecture until all students who have entered have also sitDown. 
• At any point in time, any classroom may have only one lecturer. 
• Classroom capacity should not exceed the limit. Visitors are always low in the count (less than 5). 
• Add a monitor thread to keep printing the status of each class as follows
