Read the following scenario and draw the class UML Diagram showing all attributes, methods, and relationships between these classes.

In the registration department, there is a system that manages student enrollment in courses and assigns teachers to teach those courses. Let's examine the three classes involved: Students, Courses, and Teachers.

Students:

The student class represents the individual students enrolled in the university. Each student has a unique identification number, a name, an email address, and a set of enrolled courses. The class also includes methods to add and drop courses, as well as accessing student information.

Courses:

The course class represents the different courses offered by the university. Each course has a unique identifier, a name, a description, and a list of enrolled students. Additionally, there is a reference to the teacher assigned to teach the course. The class includes methods to enroll and drop students, as well as access course information.

Teachers:

The teacher class represents the teachers employed by the university. Each teacher has a unique identification number, a name, an email address, and a list of courses they are assigned to teach. The class also includes methods to assign and unassign courses, as well as access to teacher information.
