Gennady Korotkevich is, without doubt, the best competitive programmer in the world (and arguably the best of all time). This whizkid just wrapped up another Google Code Jam title with consummate ease! Check this main site out for news (and to try out the problems, if you dare!): Google CodeJam 2016.
The great part is that you can also watch the live stream recording of the whole event here: Live Stream Recording. This is the third straight title for this amazing kid.
