Implement a class called StudentAdvanceTicket to represent tickets purchased in advance by students. A student advance ticket is constructed with a ticket number and with the number of days in advance that the ticket was purchased. Student advance tickets purchased 10 or more days before the event cost $15, and student advance tickets purchased fewer than 10 days before the event cost $20 (half of a normal advance ticket). When a student advance ticket is printed, the String should mention that the student must show his or her student ID (for example, "Number: 17, Price: 15.0 (ID required)" ).
