You might wonder: what kind of popular or controversial topic gets 175 comments?

The answer:

You are right! Codeforces edu section — Community Course! Most of the comments are "Still empty" :) But the good news is, this is not the case anymore!

I've just added the first set of tutorials on the RMQ Problem, which covers these three topics:

• Sparse Table
• SQRT Decomposition
• Disjoint Sparse Table

It's just a starting point, but hopefully, it will encourage others to contribute. Let's work together to build a high-quality collection of competitive programming materials! Check out a related comment below.

Let me know if you have any comments on the tutorials, which will help future writers as well.
