Hi everyone! I've gotten a few recommendations to start screencasting/making video solutions, and I was initially reluctant, but I realized it's kinda fun to do it. I've started out by screencasting today's Div. 3 and explaining my solution ideas at the end, arguably a bit awkwardly, but I'll get better as I get more experience with it. There are, of course, other awesome youtubers like SecondThread who do the same thing (and better), but I figured the more resources, the better for everyone.
Anyway, my first video is here. The quality's a bit bad for this one, but I know how to fix it for the future so it's just a one-time thing. In this video, you can see me spending too much time on C and F, watching my rank falling over time, and somehow still placing 14th with no mistakes. Enjoy!
As it's my first video, some of the explanations may be confusing (especially F). If you have questions about them or just feedback in general, feel free to leave comments (preferably on this blog, since there's math mode here). Expect more screencasts for the upcoming Div. 2's, contests on other sites like AtCoder and maybe CodeChef, and probably algorithm tutorials in the future.
edit: jesus christ, 100 subs in less than a day. You guys are insane, and I love you all!
