Can you solve this real interview question? Find Median from Data Stream - The median is the middle value in an ordered integer list. If the size of the list is even, there is no middle value, and the median is the mean of the two middle values. * For
Design a data structure that supports the following two operations: void addNum(int num) - Add a integer number from the data stream to the data structure. double findMedian() - Return the median of all elements so far. For example: addNum(1) addNum(2) findMedian() -> 1.5 addNum(3...
Design a data structure that supports the following two operations: void addNum(int num) - Add a integer number from the data stream to the data structure double findMedian() - Return the median of all elements so far. 简而言之,就是实现一个数据结构,可以实现插入操作,并且得到一组数的中位...
[leetcode] 295. Find Median from Data Stream @ python 原题Median is the middle value in an ordered integer list. If the size of the list is even, there is no middle value. So the median is the mean of the two middle value. For example, [2,3,4], the median......
