Segment Tree Template for Competitive Programming: Point Updates and Range Queries
The following reusable segment tree implementation uses 0-based indexing with half-open intervals [l, r). It supports point assignment, point addition, range queries, and methods to locate the first or last endex satisfying a custom predicate.
#include <bits/stdc++.h>
template<typename Info>
struct SegmentTree {
int size = 0;
