Tune in at twitch.tv/the__tourist at around 21:45 MSK, 28 Jan 2020 to watch me solving SnarkNews Winter Series 2020 Round 4 live! I'm going to do the round competitively without any interaction, and I'll try to explain the problems in English on stream afterwards.
As usual, I invite you to do the round yourself before I do! If you don't understand Russian, you may compete using automatic translators, or you may just read the problems beforehand without solving them. In any case, don't discuss the problems in Codeforces comments before the stream ends.
See you on stream!
