CodeForces - 1252H Twin Buildings(贪心)

题目链接题目大意在n块\(W\times H\)的地里建两个建筑，可以建在同一块地，也可分开，建筑与边界平行。解题思路建在同一块地很好算，主要是建在不同的地里怎么算。首先将长边从大到小排序，然后开始遍历，将当前的长边当作建筑的一边，而将之前的最长的短边与现在的短边取最小值，显

HDU4296-Buildings-贪心（说说所以然）

先讲一下题目的意思：给我们n个砖块，每个砖块有重量w和承重s，需要把这些砖块累起来。每一层的PDV值是其上所有重量减去当前的承重s，需要求的是一种排序使得总的PDV值最小。正确的排序：当第 i 块砖在第 j 块上面，应满足 p[i] - s[j] < p[j] - s[i] 当我们不知道第 i 块和第 j 块谁
