I will solve recent problems from Codeforces, mainly around div2D difficulty.

I'm going to stream on Twitch at the same time:   / errichto  .

I’m Kamil Dębowski, better known as Errichto. I compete in and organize programming competitions. I make educational streams on Youtube and Twitch. I'm a finalist of ACM-ICPC, Topcoder Open, Facebook Hacker Cup and Google Code Jam. I got a second place in Google Code Jam 2018. I am/was nutella in Codeforces and target in Topcoder.

Watch me if you want to practice for coding interviews, competitive programming or just algorithms in general. I share my thought process, explain everything, and mention similar problems and techniques/algorithms.
