Here are the pictures from today’s lecture. We recalled the 3SUM problem form the homework (due Wednesday, mind you) and looked at the search in a doubly sorted matrix as a hint for 3SUM. In that problem, we gave an algorithm for the upper bound and gave an argument for the lower bound. It turns out these bounds are tight.

Don’t forget to work on the homework! The comments section is a good place to start, but the TA office hours are also good.
Have a great weekend!
