I saw on Codeforces on a regular basis, that there are a lot of questions and answers about practicing and practicing more.
Although It is my opinion that the Educationals Rounds are best for this, at least for people like me. They learn from it and the problems are very nice and interesting.
There are many Educationals Rounds will come and I will also try my best to keep this blog update.
Although if you want to generate these links
at any time locally you can find the code on my GitHub repo: https://github.com/adshin21/Codeforces-Contest-Selector-By-Div-s
So I've collected the links for all the educationals rounds that has happened.
PS: I do not know how to place that table in the center.
If any links are broken or having some issue let me know in the comments. Happy Coding :)
