Well today I just got the notification that my rating increased by 133 points!! So now I am 1588 with only 12 left to get to EXPERT!!. Well this happened after a great div2 contest for me, (but a really shit problem C in my opinion). Not only was the solution itself kind of weird, but the majority of the time I spent coding was for the testcase where n=3. There were so many different ways to choose indices that i rlly wasn't sure if I counted them all or not. Anyways, I hope questions like C don't come again. Also, I can't help but wonder that if I solved C just a bit quicker, whether I would have gotten those 12 extra points in this contest itself. Anyways, Toodaloo.
