Also keep in mind that CS161 has a final programming project, so if your programming skills are feeling rusty, it may be worth trying some of these problems out to limber up. Details. Every Wednesday, by the end of the CS161 lecture, the problems for the week will be posted here. On Friday, we'll meet in lab to work on the problems.
