(Due to time constraints, this lecture spans 2 class periods.)

Classroom minutiae 2021-02-18

HW2 now available, due in 2 weeks: here.

• Remember to email before the deadline to use late days (either the 4 freebies or additional late days) -- so that we make sure to delay grading your assignment.

Some pain points from HW1:

• Make sure to run cargo clippy (handling all warnings) and cargo fmt!

• Part 3 problem 4: &'static str lifetime

• Part 3 problem 7: passing ownership vs. passing references
