Here is Assignment #4, composed of the collected tutorial quizzes, solutions to those quizzes, and some extra questions building on the quizzes for the assignment. (Here is LaTeX source, with a .txt extension so the blog lets us post it!)
The assignment is due on Fri 17 Nov at 10PM. HOWEVER, we expect to base some of the midterm problems on these quizzes/assignment. So, we strongly recommend that you create a solid draft solution before the exam (which may not yet be in clean enough form to submit).
Please submit it on GradeScope.
