/* poj 2528 Mayor's posters 线段树 + 离散化 离散化的理解: 给你一系列的正整数, 例如 1, 4 , 100, 1000000000, 如果利用线段树求解的话,很明显 会导致内存的耗尽.所以我们做一个映射关系,将范围很大的数据映射到范围很小的数据上 1---->1 4----->2 100----->3 1000000000----->4 这样就会减少内存一些不必要的消耗 建立好映射关系了,接着就是利用线段树求解 */ #include<ios…

http://poj.org/problem?id=2528 题意: 给出一面无限长的墙,现在往墙上依次贴海报,问最后还能看见多少张海报. 题意:这道题目就相当于对x轴染色,然后计算出最后还能看见多少种颜色. 由于数据量是给定的,所以需要进行离散化.但是这道题目的话,不能简单的离散化,前后相差大于1的话需要额外的插一个数. #include<iostream> #include<algorithm> #include<cstring> #include<cstdi…

点我看题目 题意 :建一堵墙粘贴海报,每个候选人只能贴一张海报,海报的高度与墙一样高,一张海报的宽度是整数个单位,墙被划分为若干个部分,每个部分的宽度为一个单位,每张海报完全的覆盖一段连续的墙体,墙体的宽度占整数个单位.因为候选人将海报贴到墙上的时候可能会将别人的覆盖或覆盖一部分,给出海报的大小,选举墙上张贴的位置,和张贴的次序,然后问你最后还能看到几张海报. 思路 : 这个墙因为有10000000单位长,而n最大有10000,所以要先进行离散化,但是离散化之前要先将数字存起来,排序之后再将每相…
