Hi everyone. I recently started learning Segment Tree. So now I want to solve more problems with Segment Tree in Codeforces. Can you suggest me some problems similar to a Segment Tree, like896E - Welcome home, Chtholly? So I can improve myself? Thanks in advance!
The segment tree is a very useful algorithm when doing many RMQ problems, we have the following problem: https://codeforces.com/contest/1199/problem/D how to solve it? Well, here is the segment tree to help us, but what is the segment tree? Well, it is a tree where each node is ...

Today, Segment Tree takes revenge on you. As Segment Tree can answer the sum query of a interval sequence easily, your task is calculating the sum of the sum of all continuous sub-sequences of a given number sequence. Input The first line contains a single integer T, indicating the number...
https://codeforces.com/contest/1278/problem/D 题意: As the name of the task implies, you are asked to do some work with segments and trees. Recall that a tree is a connected undirected graph such that there is exactly one simple path between every pair of its vertices. ...
