/*Problem Statement

Your task is to implement a recommendation algorithm that takes in a student's past courses and

ratings, and returns a list of recommended courses based on the following criteria:

• Courses that the student has already taken and rated highly (4 or 5) should be given higher

priority in the recommendations.

• Courses that are related to the student's past courses (e.g. same subject or level) should be

given higher priority in the recommendations.

• Courses that have been highly rated by other students should be given higher priority in the

recommendations.
