Write a method, computeTicketCode, that receives a vehicle\'s speed(int) detected by radar camera , and a boolean(isSchoolZone). Return appropriate code depending on received values as described below:

method signature: public static int computeTicketCode(int speed, boolean isSchoolZone)

When NOT in a school zone: (false value received for isSchoolZone)

speed code

0-30 0

31-59 1

60-75 2

75+ 3

When IN a school zone (true value received for isSchoolZone)

speed code

0-20 0

21-50 1

51-60 2

61+ 3
