http://poj.org/problem?id=3264 题意:给出n个数,还有q个询问,询问[l,r]区间里面最大值和最小值的差值. 思路:RMQ模板题,开两个数组维护最大值和最小值就行. #include <cstdio> #include <cstring> #include <cmath> #include <algorithm> using namespace std; #define N 50010 #define INF 0x3f3f3f3…

RMQ支持操作: Query(L, R):  计算Min{a[L],a[L+1], a[R]}. 预处理时间是O(nlogn), 查询只需 O(1). RMQ问题 用于求给定区间内的最大值/最小值问题..询问的次数多的时候 好用.. 这个题目我至少得开数组开到 80000才能过,不知道为什么..刚开始还写错了,贡献了好多RE和WA.. 题目:http://poj.org/problem?id=3264 题意:给n个数,q次询问,求最值的差.. #include <iostream> #incl…

Balanced Lineup poj3264 线段树 题意 一串数,求出某个区间的最大值和最小值之间的差 解题思路 使用线段树,来维护最大值和最小值,使用两个查询函数,一个查区间最大值,一个查区间最小值,然后做差就好了,基本上就是线段树模板题 代码实现 #include<cstdio> #include<cstring> #include<algorithm> using namespace std; typedef long long ll; const int i…

P1360 [USACO07MAR]Gold Balanced Lineup G (前缀和+思维) 前言 题目链接 本题作为一道Stl练习题来说,还是非常不错的,解决的思维比较巧妙 算是一道不错的题 思路分析 第一眼看到这题,我还以为是数据结构题,看来半天没看出来数据结构咋做(我还是太菜了) 我们对\(m\)种能力有\(n\)次操作,需要找到对每种能力提升相同的最大操作区间的长度,求最大 区间,我们考虑维护这\(m\)种技能提升值的前缀和,假设第\(l+1\)次操作到第\(r\)次操作对\(m\…
