Правка en2, от orz, 2023-09-19 00:07:13

Today a horrible thing almost happened: I barely stayed an International Grandmaster on Codeforces after participation in CodeTON Round 6 (Div. 1 + Div. 2, Rated, Prizes!). I would't say I was exceptionally slow or that I solved problems too clumsily, but for some reason the majority of participants near my level were faster than me on these problems.

I recorded a five hour long video about my adventures. If you're interested in a particular problem, follow the timecodes:

Problem Solving Implementation Editorial
1870A - МЕХанизированный массив 01:37 02:45 3:23:28
1870B - Дружные массивы 06:23 10:54 3:30:20
1870C - Разноцветная таблица 12:48 14:12 3:41:00
1870D - Покупка префиксов 22:14 24:41 3:58:20
1870E - Очередная задача на MEX 39:37 58:42 4:34:24
1870F - Ленивые числа 1:31:03 2:54:32 2:30:37

If you open a video and see it's low quality, you might want to wait several minutes until YouTube processes the higher resolutions.
