Exam Review
Past exams
The following are the practice and real exams prepared for various versions of the course. Even though in some semesters we may have explained a few ideas slightly differently, these should be considered good practice problems.
Sometimes exams contained typos, resulting in more lenient grading that the key would indicate. In some, but not all, cases those typos were corrected before being posted here.

;and it should returnint, notshort(typos). - For question 20, we want to move
Programming!instead ofProgramming.
