题目链接:hdu 3255 Farming 题目大意:给定N个矩形,M个植物,然后给定每一个植物的权值pi,pi表示种植物i的土地,单位面积能够收获pi,每一个矩形给定左下角和右上角点的坐标,以及s,s表示该矩形能够中植物s.问说总的最大收益. 解题思路:由于一块仅仅能种一种植物,所以对于一块重叠的土地,要选取收益最大的植物种植.除去这一点,剩下的就是线段树扫描线的应用了.那对于pi能够视为第三维坐标,而植物的种类仅仅有3种,所以直接离散化就可以,注意要依照植物收益的权值大小离散. #inclu…

题意:在一块地上种蔬菜,每种蔬菜有个价值.对于同一块地蔬菜价值高的一定是最后存活,求最后的蔬菜总值. 思路:将蔬菜的价值看做高度的话,题目就转化成求体积并,这样就容易了. 与HDU 3642 Get The Treasury 同样求体积并,只不过HDU 3642 是要求覆盖大于等于3次的体积并,该题比那道题容易些. 先将蔬菜价值(即高度)从小到大排序,然后一层一层地开始扫描,计算每层中的面积并,这个就同二维扫描一样.   然后再用面积乘以这层的高度,即得到该层的体积并.然后所有层的体积加起来,即…

做了这么多扫描线的题,,基本都是一个思路. 改来改去,,无非就是维护的节点的内容以及push_up越写越复杂了而已 首先将价格排序处理一下编号,变成编号越大的powerfol越大 然后后面加入扫描线的时候将旧编号直接转换成新编号即可了 对于这题 S[rt][i]维护的是.rt节点相应的区间中品种为i的长度 S[rt][i]维护的是.rt节点相应的区间的品种为i出现的次数 那么,假设出现了cnt[rt][3],就将S[rt][3]赋值为区间长度,S[rt][1]和S[rt][2]都赋值为0,由于已…
