Competition Overview The problem difficulty is generally estimated as F < A = J = I < L = G = E < C = K = H. The contest featured a mix of standard algorithms and optimization problems. Below is the detailed analysis and solution for each problem. Problem F: Prefix Sum Threshold Problem Statement:Given an initial score of 1500 and a sequence o ...

Problem A: Honest or Dishonest Two characters (a) and (b) are given, each either H (honest) or D (dishonest). Person A always tells the truth if (a = H), otherwise always lies. A states that B is honest if (b = H), or that B is dishonest if (b = D). Determine whether B is actually honest. Solution If A is dishonest ((a = D)), the statement is f ...

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; ...
