CS212 Preliminary Exam I
Name: SAMPLE KEY Id:

• There are five (5) parts to this exam. Please check now that you have a complete exam booklet with twelve (12) numbered pages.
• Write your name and id number on each page of the exam.
• Be sure to try all of the problems, as some are more difficult than others. Don't waste a lot of time on a problem that is giving you a hard time - move on to another problem and then return to it later.
• This exam is closed book. No papers, books, notes, or computational devices may be used. However, we will provide you with a copy of the Dylan quick reference sheet.
• There is space provided to answer each question. Ask for an extra piece of paper if you need more space to answer a problem.
• The staff reserves the right to ignore illegible answers. Proper indentation of any code you write will aid in the grading process.
• Many problems ask for an answer without any justification. If you feel uncomfortable with your answer, feel free to add justification. Very often, an incorrect answer with justification will receive some credit.
