Be warned that old courses might have covered different material and used different policies for exams. For example, at least the following were changed in Spring 2009: quicksort uses the first element as the partition element; shellsort uses a different increment sequence; red-black BSTs are left-leaning 2-3 trees; KMP and grep implementations are completely different; and LZW uses a different starting code.

Exam policy.   Exams are closed book and closed note, although you are permitted to bring one 8.5-by-11 cheatsheet, written in your own handwriting. No calculators or computational aids are permitted.
