滑动窗口(sliding window)方法是一种在序列数据(如字符串、数组等)中找到满足特定条件的 连续子序列的算法。滑动窗口方法的核心思想是使用两个指针(通常称为左指针和右指针)表示当前的窗口。在遍历过程中,…
By using HashSet as a sliding window, checking if a character in the current can be done in O(1). A sliding window is an abstract concept commonly used in array/string problems. A window is a range of elements in the array/string which usually defined by the start and end indices, i...
This median can be computed in different ways — but in“leetcode” the task statement notation median is: middle element of the ascendant ordered sliding window ( if elements counts is odd ) average of two elements in the middle the ascendant ordered of sliding window ( if elements count is...
