I managed to finish A1 and Problem set #2 over the weekend. Feels good to have them off my back. Problem set #2 was pretty straight forward, Prof Heap gave an example in one of the lectures that helped a lot. I had more trouble with A1 especially Q2 with the lunch menus. I couldn't find a pattern between the lunch menus, or i didn't try hard enough. Either way I spent most of my time staring at this question and trying to make a menu for n>3 items. I looked to a friend for help and he pointed me in the right direction, giving me insight on how he found the pattern. After that it took a few minutes to devise and prove a technique and then I was done. Now to study for the midterm and hope for the best, good luck everyone.
