点我看题目 题意 :N头奶牛,Q次询问,然后给你每一头奶牛的身高,每一次询问都给你两个数,x y,代表着从x位置上的奶牛到y位置上的奶牛身高最高的和最矮的相差多少. 思路 : 刚好符合RMQ的那个求区间最大最小值,所以用RMQ还是很方便的.就是一个RMQ的模板题,基本上书上网上都有. RMQ基础知识 RMQ算法举例 #include <stdio.h> #include <string.h> #include <math.h> #include <iostream…

Description 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 rang…

题目链接: Poj 3264 Balanced Lineup 题目描述: 给出一个n个数的序列,有q个查询,每次查询区间[l, r]内的最大值与最小值的绝对值. 解题思路: 很模板的RMQ模板题,在这里总结一下RMQ:RMQ(Range Minimum/Maximum Query) 即区间最值查询,是指这样一个问题:对于长度为n的数列A,回答若干询问RMQ(A,i,j)(i,j<=n),返回数列A中下标在i,j之间的最小/大值. RMQ有三种求法:1:直接遍历查找,炒鸡暴力: 2:线段树也可以解…
