[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 elements so far. For example: addN...
[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......
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
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. 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...
findMedian() -> 2 【解题思路】 最简单的做法是直接把数据放到ArrayList中,每次计算Median时先对ArrayList排序,然后计算Median 1classMedianFinder {23privateArrayList<Integer> nums =newArrayList<Integer>();45//Adds a number into the data structure.6publicvoidaddNum(intnum) {7nums.add(num);8}910//Re...
