    Hi Errichto. I love your videos so keep it up. I’ve been trying to do leetcode easy problems and have trouble with them so I’m super stuck on what to do and don’t know where to start. Any suggestions?

    Congrats for the 7th place. One step away from the final round, best of luck with it.
    Can I ask you why did you multiply by 2 at 17:07 ? I understand the solution but couldn't get this little part.

    • @Errichto
      @Errichto  3 роки тому +12

      Good question!
      There's probability 1/total that we choose this player first, then prob. worse/(total-1) that we choose one of worse players. But I also want to consider choosing a worse player first, then myself. The formula should be 1/total*worse/(total-1) + worse/(total-1)*1/total but I can just multiply by 2.

    hey Errichto, not trying to be a dick or anything.. but can you make your camera image smaller next time? it covered a decent portion of the code, thanks for the amazing videos!

    • @Errichto
      @Errichto  3 роки тому +47

      Sorry about that. I recorded something else a few days ago and forgot to change the camera image size back to normal like in previous screencasts. Will do next time!

      There's no point of trying to win if you just need to qualify. That's probably what happened with Gennady and Petr. They know that they can get top 200.

    Your short videos were much more useful. Such long videos are also useful, but sometimes. Now most of your videos are very long and not educational unlike your short videos
