Hi all, I'm planning to do a stream this weekend (edit: now in the past), focusing on problems in Number Theory.

I've put together a mashup of 12 problems (ordered by difficulty), which is available here: https://codeforces.com/contestInvitation/8305134301b2607eaa233fc638ac5fbf91a5c82e (thanks jschnei and neal for problem suggestions and feedback).

Try to solve them on your own! We'll go over those problems & their solutions on stream. Also, feel free to suggest any other number theory problems or concepts you'd be interested in, and I'll try to take a look on stream.

My stream can be found in the sidebar, and you can also follow me directly on Twitch. I upload my streams (afterwards) to YouTube as well, so feel free to subscribe there if you'd like to watch them later!

Edit: I've published this (with timestamps) on YouTube: https://youtu.be/VoD5Mt3Bdec

For what rating range of people is this most relevant?

Reminder that this is in approximately 22 hours! Take a look at the problems & try to solve them if you have time. :)

    feel free to suggest any other number theory problems or concepts you'd be interested in

    How to approach medium to hard combinatoric counting problems, like inclusion exclusion of rating around 2000 or above not requiring very high math but thinking, for example from atcoder contests

      Since that isn't Number Theory, I'll probably save it for a future stream, but I'm definitely interested in doing a combinatorics & expected value stream -- that's a topic I like a lot. Thanks for your suggestion!

    It's available at https://www.youtube.com/watch?v=VoD5Mt3Bdec, though I still have to add timestamps (for the start of each problem) and links (for each problem on CF, not in the gym, so you can see the problems without an account).

    If you or anyone else wants to write those and PM them to me, I would appreciate it. :)

    (Otherwise I'll do it at some point when I get a chance, and then publish the video.)

It's published on YT now (with timestamps). I've edited the link into the blog post.

Thanks everyone for participating! It looks like people are still submitting to the mashup, which is great to see -- practice is the best way to improve.
