Happy Monday!

- Trees (of the dead, organic variety)
    - (9AM only) If nobody in your group wants the paper copies of E / P, leave them for teh next section
    - If someone will typically have a laptop and you're fine reading the problems from there, let me know
    - Let me know if you plan to do either of these so I can kill fewer trees

- Discord: I was going to make a Discord server, but someone beat me to it. I'm happy to lurk, answer questions, and informally use the server, assuming:
    - Everyone in the class has been / can be invited
    - Everyone follows the student code of conduct


- Runtime question:
    - Is calling a method (not counting whatever the body of the method does) a constant-time operation? Yes.
