http://poj.org/problem?id=1151 经典矩形面积并吧.....很简单我就不说了... 有个很神的地方,我脑残没想到: 将线段变成点啊QAQ这样方便计算了啊 还有个很坑的地方,为毛每一次我精确地计算过空间可就是wa....一改大就ac...我无力了.. #include <cstdio> #include <cstring> #include <cmath> #include <string> #include <iostrea…

[POJ1151]Atlantis(线段树,扫描线) 题面 Vjudge 题解 学一学扫描线 其实很简单啦 这道题目要求的就是若干矩形的面积和 把扫描线平行于某个轴扫过去(我选的平行\(y\)轴扫) 这样只需要求出每次和\(x\)轴覆盖的长度 就可以两两相乘,求出面积 最后累计和就行啦 #include<iostream> #include<cstdio> #include<cstdlib> #include<cstring> #include<cma…
n个矩形,可以重叠,求面积并. n<=100: 暴力模拟扫描线.模拟赛大水题.(n^2) 甚至网上一种“分块”:分成n^2块,每一块看是否属于一个矩形. 甚至这个题就可以这么做. n<=100000 这就要到扫描线了. 之前一直不会. 不好处理的地方在于:不知道区间被覆盖怎么计算.... 像sum区间和一样计算??sum>区间长度也不一定完全包含... 不管覆盖多少次,就只算一次??之后的减法怎么算?? 总之, 这篇题解打消了我的疑惑:ACM POJ1151 (HDU 1542) Atl…

这个题算是我的第一个扫描线的题,扫描线算是一种思想吧,用到线段树+离散化.感觉高大上. 主要参考了这位大神的博客. http://www.cnblogs.com/kuangbin/archive/2012/08/15/2640870.html HDU1542 Atlantis(线段树:扫描线) http://acm.hdu.edu.cn/showproblem.php?pid=1542 分析: 首先假设有下图两个矩阵,我们如果用扫描线的方法如何计算它们的总面积呢? 首先我们将矩形的上下边分为上位…
