I started at dawn with no idea what to do, but it was so fun that I stayed up all night, came home tired after running errands, and did a little more in the afternoon, and I finally finished it. I solved all the basic select problems on Hacker Ranker, and they were so fun..!! I'm half worried and half excited about whether I'll be able to do well without giving up at the intermediate level, but.. I'll do my best. Thank you for the great lecture.
