Recently, the Computer Engineering Department has launched its professional education under the title of “Micromasters”, which has been well received by audiences from various universities. Undoubtedly, the quality of these classes played a significant role in this reception. One of the quality factors is to limit the number of registrations for a class. Although the registration for this semester has ended, the director of professional education has decided to limit the number of registrations for each class to 50 and make an urgent decision for the classes with more than 50 students registered. Help the director of professional education to identify which classes have more than 50 students registered.
