Notice, I publish the videos AFTER the contest has ended, even though, we solved the contest way before it ended. This is to avoid cheating! Since I was out of the competition, I didn't really care if I got wrong answers. If I were to compete for rating points, I would be much more careful in testing the problems for edge cases.
Also, check out the other videos on my channel including CodeForces, AtCoder, and COCI recordings, cool graphical explanations, and live streams where we delve deeper into interesting concepts in competitive programming.
