CSES - Range Update Queries

Can convert any point update range query -> range update point query. Here we use a segment tree; a BIT would also work.

1#include <bits/stdc++.h>
2using namespace std;
3 
4using ll = long long;
5using ld = long double;
6using db = double; 
7using str = string; // yay python!
8
9using pi = pair<int,int>;
10using pl = pair<ll,ll>;
