Errichto Algorithms
Algorithms, competitive programming, coding interviews. I make educational videos and coding live streams, always sharing my thought process.
My name is Kamil Dębowski (or Errichto) and I'm quite good at competitive programming. I'm a finalist of multiple big programming competitions like ICPC, Facebook Hacker Cup and Google Code Jam (even got 2nd place in 2018). I also organize competitions, which means inventing and preparing problems.
