This one's familiar: rewrite the
which program (assigned in CSci 428 Homework 3, I believe…maybe HW 4 the year you took it) in Rust. The main issue is to find a replacement for
strtok, but there should be some nifty string processing libraries already there. However, in 5 minutes of searching, I didn't come up with anything, so it may need to be done by hand! Or, could be a job for nix.
