Educational Codeforces Round 83 Explanations

You might be wondering why I didn't upload a screencast. That's because I accidentally turned on my facecam when I recorded it, and I'm not sure if I want to make it public :/ I'm 8th by the end of the contest though, which is pretty decent. If you have any questions, please ask them in the comments below, so that I can improve my explanations as well! If this was helpful, consider liking or subscribing!
