Final Exam Information:

Time: May 2 (Thursday) 3:00-5:00pm

---
Format: same as the midterm

Short answer questions (60 points) and long answer questions
(40 points). One 20-point long answer question on Assignment 3.

All questions are related to the materials after midterm; some may touch
the subjects before midterm. 

There is at least one candidate question for the subjects in each lecture. 

Most questions are coding questions: writing code segments to achieve
certain tasks or predicting the output of a code segment (concepts are
embedded in such questions).
