Hello everyone!

I just published a new lesson in the EDU section. This is the first part of the lesson about the segment tree.

In this lesson, we will learn how to build a simple segment tree (without mass modifications), and how to perform basic operations on it. We will also discuss some tasks that can be solved using the segment tree.

Go to EDU →

More about EDU section you can read in this post.

Hope it will be helpful, enjoy!

      There is a bug in normal friends standings for a particular problem, after selecting friends only checkbox , we can't sort the standings other than based on solution size, please fix this soon. Example: https://mirror.codeforces.com/contest/1380/status/A?friends=on open this url, and try sorting according according to execution time or submission time, it redirects to /status route.

      Thankss

This thing is really great and helpful. Hoping for more tutorials on topics that are more likely to be used to solve problems of difficulties around 1600-1900 ratings.

And also, thanks a lot for your time and hard work. Really appreciate it :)

the astute reader will note that these videos are being released only now that antontrygubO_o has banned use of data structures in contests. Coincidence? I think not
