In a private university, students can enroll for at least 1 to a maximum of 5 subjects in a semester. Subjects that are to be offered in that particular semester will be assigned to a class. One class should have at least 5 students and up to a maximum of 40 students. Multiple classes for a subject can be created if the student number enrolled for the subject is large. A subject might not be offered on that semester depending on the needs. A lecturer can be assigned to zero and up to a maximum of 4 classes on that particular semester.

Draw the class diagram to represent the above scenario. Each entity should have at least ONE (1) attribute as its identity. Provide the relevant associations between these entities and include the multiplicities.
