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...
