C++ multiset通过greater、less指定排序方式，实现最大堆、最小堆功能

STL中的set和multiset基于红黑树实现,默认排序为从小到大. 定义三个multiset实例,进行测试: multiset<int, greater<int>> greadterSet; multiset<int, less<int>> lessSet; multiset<int> defaultSet; ; i < ; i++) { )); greadterSet.insert(v); lessSet.insert(v); def…

Google 面试题：Java实现用最大堆和最小堆查找中位数 Find median with min heap and max heap in Java

Google面试题股市上一个股票的价格从开市开始是不停的变化的,需要开发一个系统,给定一个股票,它能实时显示从开市到当前时间的这个股票的价格的中位数(中值). SOLUTION 1: 1.维持两个heap,一个是最小堆,一个是最大堆. 2.一直使maxHeap的size大于minHeap. 3. 当两边size相同时,比较新插入的value,如果它大于minHeap的最大值,把它插入到minHeap.并且把minHeap的最小值移动到maxHeap. ...具体看代码 /***********…
