一秒转为毫秒是 1000,所以 1000 就称为窗口时间大小(windowLengthInMs)。 windowStart + windowLengthInMs = 时间窗口的结束时间 只要知道时间窗口的开始时间和窗口时间大小,只需要给定一个时间戳,就能知道该时间戳是否在 Bucket 的窗口时间内,代码实现如下。
Sliding window algorithm is used to perform required operation on specific window size of given large buffer or array. 滑动窗口算法是在给定特定窗口大小的数组或字符串上执行要求的操作。 This technique shows how a nested for loop in few problems can be converted to single for loop and hence reduci...
POJ 2823 Sliding Window 单调队列优化 滑动窗口 【题意】 n个数,现在有一个大小为w的划窗,窗口每个时刻向后移动一位,求出每个时刻窗口中数字的最大值和最小值。 【解题方法】 求最大值:建立一个单调递减队列,元素从左到右依次入队,入队之前必须从队列尾部开始删除那些比当前入队元素小或者相等的元素,直到遇到...

To check if a character is already in the substring, we can scan the substring, which leads to an O(n^2)O(n2) algorithm. But we can do better. By using HashSet as a sliding window, checking if a character in the current can be done in O(1). ...
We are going to add the first three elements in the array starting from index 0 moving to the next element continuously. When we add the next subset, we will move the window by subtracting the start index element and adding the new index element....

a client could send 100 requests in the last second of the first minute and another 100 requests in the first second of the second minute, resulting in 200 accepted requests in 2 seconds. This library supports a flexible sliding window algorithm based on Redis backend which solves this problem...
