Hi everyone,
It is clear that for better or worse, Codeforces is turning into Mathforces.
The recent https://codeforces.net/contest/2020 is a clear example of this. Problem B is a well known math puzzle, and Problem A is just base systems.
This means that competitors who are knowledgeable in math will have a substantial advantage.
Get the math edge through this amazing coding/math resource. We will train both your problem solving skills AND your coding skills, which will be a formidable combination in competitions.
I will probably lose a lot of contribution due to this, but I just wanted to help the community learn that slowly, Mathforces will dominate Codeforces.
Thank you, Sub_to_MegaMath_Channel
