Java: Find the median of the number inside the windowLast update on April 01 2025 10:50:08 (UTC/GMT +8 hours)Median in Sliding WindowWrite a Java program to find the median of the numbers inside the window (size k) at each step in a given array of integers with duplicate numbers. ...
findMedian() -> 2 https://leetcode.com/problems/find-median-from-data-stream/ 找出中位数,暴力O(n^2)超时。 O(nlogn)的做法是开两个堆(java用优先队列代替)。 最小堆放小于中位数的一半,最大堆放较大的另一半。 addNum操作,把当前的num放到size小的堆中,通过2次poll-add操作,保证了最小堆中的...
[2,3,4], the median is3 [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...
double findMedian()- Return the median of all elements so far. For example: add(1) add(2) findMedian() -> 1.5 add(3) findMedian() -> 2 最大最小堆 复杂度 时间O(NlogN) 空间 O(N) 思路 维护一个最大堆,一个最小堆。最大堆存的是到目前为止较小的那一半数,最小堆存的是到目前为止...
大家好,欢迎阅读金猪Ethan的JAVA小课堂。虽说是JAVA小课堂,但其实是梳理自己的JAVA做题笔记,理清思路,加深记忆,欢迎跟我一起学习。 今天我们继续挑战一道Hard题。我们需要创造一个MedianFinder的class,创造c…
public class findMedian { public static void main(String[] args){ MedianFinder obj = new MedianFinder(); obj.addNum(1); System.out.println(obj.findMedian()); obj.addNum(3); System.out.println(obj.findMedian()); obj.addNum(2); ...
建议和这一道题leetcode 480. Sliding Window Median 滑动窗口中位数 一起学习 代码如下: import java.util.Collections; import java.util.PriorityQueue; /* * 用一个最大堆存放比中位数小(或等于)的元素,用一个最小堆存放比中位数大(或等于)的元素。

Using simple Java techniques to find median In our first example, we will use a basic Java approach to calculate the median. For these examples, we have modified our testData array slightly: double[] testData = {12.5, 18.3, 11.2, 19.0, 22.1, 14.3, 16.2, 12.5, 17.8, 16.5}; First, ...
