Hello all,
Are there any good (yet basic) problems that use a segment tree of dsus? I've been reading a lot of problem tutorials that use this as the solution, but I don't really understand how it works. I was hoping to start out with simpler problems and gradually work to the harder problems.
However, when I tried searching the topic up on google, the closest thing I could find was an article that briefly mentioned combining segment trees and dsus but failed to explain it for a beginner.
The example problem is here: https://codeforces.me/contest/763/problem/E
Any recommendations would be greatly appreciated!
can you share the problem whose editorial you were trying to read. because i know only one problem 76-A that uses segment tree of dsu
[Comment Edited]
And how this problem can be solved using Segment tree of DSU? ( about problem in blog 763D)
I even don't understand why you think that it is possible.
Sorry, I put the wrong problem in.

1140F? Sorry for my bad English, I don't know what data structure you are talking about.
No worries, this looks like a similar problem.
Thanks for the response!
