AK爷GhostCai的电脑又蓝屏了Orz 贪心题,确定一个maxh,限定h不大于一个值.枚举maxh. check的时候的细节很多: 1.h>maxh但w<maxh交换的时候需要占用交换名额. 2.cnt<0了就应该return -1了... 突然忘记还有啥细节 代码如下 #include <iostream> #include <algorithm> #include <cstdio> using namespace std; const int…

传送门 解题思路 这道题要用到贪心的思路,首先要枚举一个h的最大值,之后check.如果这个东西的w[i]与h[i]都大于枚举的值就直接return false,如果w[i]比这个值小,h[i]比这个值大,就将h[i]与w[i]交换,注意并不能直接交换因为后面还要用到,要在答案中将h[i]加上.如果交换次数比n/2大也return false,如果w[i]与h[i]均比这个值小,则将w[i]-h[i]加入数组.后面将它排序,选出可以被交换的更新答案. 代码 #include<iostream>…
