35 FINAL EXAM (2023) - Questions to study
35.1 About these questions/answers
The answers to each question were written to explain how to think about arriving at the answer.
The actual answer is on the line containing the comment #ANSWER. All other lines are there to demonstrate the answer working on actual data or to demonstrate portions of the whole answer so that the whole answer is more easily understood. If the actual required code for an answer takes up several lines then the comment will say #ANSWER (MULTIPLE LINES).
If different possible answers are shown, then the different answers will be displayed with the comment #ALTERNATE ANSWER or #ANOTHER ANSWER.
Note that it is very possible that there are valid answers other than the ones shown below.
35.2 Final Exam
The final is cumulative in that you MUST KNOW the material from before the midterm in order to be able to answer questions that cover material from after the midterm. See below for the list of questions from the midterm material.
With that said, ALL of the questions on this website are good study material for the final.
For your convenience I listed below those questions on this website that were not listed in the study material for the midterm.
There are plenty of practice questions here but I will try to continue to post additional practice questions.
