结果非常理想,竟然击败了100%的人,用时36ms,不得不说Sliding Window algorithm用O(n)的时间复杂度就可以解决substring searching的问题,非常非常有效。强烈建议理解这种方法。 Minimum Window Substring Given a string S and a string T, find the minimum window in S which will contain all the characters in ...
在LeetCode写题目的时候评论区看到一个方法,一开始没看懂,后来查了一些资料整理了一下。原题见文中例3 什么是滑动窗口算法? The Sliding Problem contains a sliding window which is a sub – list that runs over a Large Array which is an underlying collection of elements. 滑动窗口算法可以用以解决数组/...

滑动窗口算法精讲(Sliding Window Algorithm) 简介 滑动窗口算法的本质是双指针法中的左右指针法,所谓滑动窗口,就像描述的那样,可以理解成是一个会滑动的窗口,每次记录下窗口的状态,再找出符合条件的适合的窗口。它可以将双层嵌套的循环问题,转换为单层遍历的循环问题。使用两个指针一左一右构成一个窗口,就可以将二维...
LeetCode 239:滑动窗口最大值 题意 大小为 k 的滑动窗口从整数数组 nums 的最左侧移到最右侧,只能看到滑动窗口中的 k 个数字,窗口每次向右移动一位。 返回滑动窗口的最大值。 示例 提示 1 <= nums.length <= 10^5 -10^4 <= nums[i] <= 10^4 1 <= k <= nums.length 题目解析 滑动窗口最大值...
滑动窗口算法(Sliding window algorithm) 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...
We need to consider a specific aggregation algorithm known as median computation. 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 ) ...
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). ...
