I will be streaming a discussion of the problems in January Lunchtime 2020 right after the contest ends. I will go over most of the problems in div 2 and the ones in div 1 that I’m able to solve. I will also try my best to answer questions that arise during the discussion. Please note that I will not prioritize answering general questions like “how to become good at cp” (at least not during the stream).
The link will be posted below about 5 minutes after the contest ends and I will start discussing 5 minutes after that.
Instead of going through the problems in order of difficulty, I think I should go through the most requested problems first, so here’s a poll to vote: https://poll.ly/#/Gllyn9bd
