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…

For the daily milking, Farmer John's N cows (1 ≤ N ≤ 50,000) always line up in the same order. One day Farmer John decides to organize a game of Ultimate Frisbee with some of the cows. To keep things simple, he will take a contiguous range of cows fr…

题目链接:http://poj.org/problem?id=3264 一排牛按1~n标号记录重量,问每个区间最重的和最轻的差值. 线段树维护当前节点下属叶节点的两个最值,查询后作差即可. #include <algorithm> #include <iostream> #include <iomanip> #include <cstring> #include <climits> #include <complex> #includ…

本文出自:http://blog.csdn.net/svitter 题意:在1~200,000个数中.取一段区间.然后在区间中找出最大的数和最小的数字.求这两个数字的差. 分析:按区间取值,非常明显使用的线段树. 区间大小取200000 * 4 = 8 * 10 ^5; 进行查询的时候.注意直接推断l, r 与mid的关系就可以.一開始写的时候直接与tree[root].L推断,多余了, 逻辑不对. #include <iostream> #include <stdio.h> #i…
