Today was an excellent class day!

CS21A: Dr. Sarmenta went through half of Java Basics. I did too.
Students nodding. Assigned bank account and converter as homework so
that they’ll have questions on Friday.

CS110: Induction went more smoothly than I expected. Whee! I gave them
the sum(2n – 1) = n * n problem. They finished quickly. It was good
that I solved both problems in advance.

CS139.3: Fun discussion of the two problems from the minicontest.
Neill shared his solution. Learned something new. (He stored
everything as strings!) I told them about my hashtable/vector hack,
and got appreciative ooohs. Also taught them how to justify text
and read lines flexibly.

Good class day.
