一.技术总结 最开始的想法是直接用一个vector容器,装下所有的元素,然后再使用sort()函数排序一下,再取出中值,岂不完美可是失败了,不知道是容器问题还是什么问题,就是编译没有报错,最后总是感觉不对,在PAT测试点也显示段错误.最后看别人的办法了.大部分是先判断出来中值的位置,然后存储两个数组,最后进行比较,当出现了小于median值的位置的时候那么就可以输出该数了. 二.参考代码 #include<iostream> #include<algorithm> using na…

这个是原先AC的代码,但是目前最后一个样例会超内存,也就是开不了两个数组来保存两个序列了,意味着我们只能开一个数组来存,这就需要利用到两个数组都有序的性质了. #include <iostream> #include <cstdio> #include <algorithm> #include <string.h> #include <cmath> #include <queue> using namespace std; /* 水死…
