I wanted to make a video on a cool problem, which also happened to be the problem that let me become red. It also ended up turning into a story about that contest and what happened leading up to solving it, including baby trucks, broken problem difficulties, and traveling to the past to see mid-contest rankings. I think some here are interested in stories, so I'm posting this here for those who are. The video is here.

Crazy to see myself in third during the 1h mark LOL. You could've mention also that most solutions for F got hacked (even the author's solution) because the tests weren't good against slow-ish max flow implementations to paint the picture of absolute chaos that was that contest.

    Oh yeah, good point — I remember being scared that those TL issues would force an unrate, and it must have been worse to have F be your main source of points along with that.

    By the way, you held 2nd for a bit around the 58 minute mark — very impressive F
