If you are looking out for summarizing your data, you would probably start by calculating the mean (or average), the median, and the mode of the data. Finding the centralized data (known as central te, How to Find Mean Mode and Median in Python for Data
[2,3,4], the median is 3 [2,3], the median is (2 + 3) / 2 = 2.5 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 eleme...

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. 描述 中位数是有序列表中间的数。如果列表长度是偶数,中位数则是中间两个数的平均值。
When a new integer comes up, apply binary search to insert the integer in its correct position. Now, the list is sorted and you can find the median. C++ Implementation class MedianFinder { vector < int > store; public: void addNum(int num) { ...
double findMedian() - Return the median of all elements so far. Example: addNum(1) addNum(2) findMedian() -> 1.5 addNum(3) findMedian() -> 2 此题要找出数据流的中位数,数据流由无序整数组成,并且数据流是在变化的。中位数的定义是,如果数字个数为偶数,中位数就是中间两个数的平均数,如...
LeetCode 0295 - Find Median from Data Stream dataintegerlistmedianstructure 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. ...
