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. Examples: [2,3,4] , the median is 3 [2,3], the median is (2 + 3) / 2 = 2.5 Given an a…

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. 例如, [2,3,4] 的中位数是 3 [2,3] 的中位数是 (2 + 3) / 2 = 2.5 设计一个支持以下两种操作的数据结构: void addNum(int num) - 从数据流中添加一个整数到数据结构中. double findMedian() - 返回目前所有元素的中位数. 示例: addNum(1) addNum(2) findMedian() -> 1.5 addNum(3) findMedian…

滑动窗口中位数 中位数是有序序列最中间的那个数.如果序列的大小是偶数,则没有最中间的数:此时中位数是最中间的两个数的平均数. 例如: [2,3,4],中位数是 3 [2,3],中位数是 (2 + 3) / 2 = 2.5 给出一个数组 nums,有一个大小为 k 的窗口从最左端滑动到最右端.窗口中有 k 个数,每次窗口移动 1 位.你的任务是找出每次窗口移动后得到的新窗口中元素的中位数,并输出由它们组成的数组. 例如: 给出 nums = [1,3,-1,-3,5,3,6,7],以及 k = 3…

Storm Windowing 简介 Storm可同时处理窗口内的所有tuple.窗口可以从时间或数量上来划分,由如下两个因素决定: 窗口的长度,可以是时间间隔或Tuple数量: 滑动间隔(sliding Interval),可以是时间间隔或Tuple数量: 要确保topo的过期时间大于窗口的大小加上滑动间隔 Sliding Window:滑动窗口 按照固定的时间间隔或者Tuple数量滑动窗口. 如果滑动间隔和窗口大小一样则等同于滚窗, 如果滑动间隔大于窗口大小则会丢失数据, 如果滑动间隔小于窗…
