主要有以下两个常见类型的滑动窗口问题: 1.给定窗口大小 2.最小最大类问题 原理分析 举例1:给定一个字符串 S 和一个字符串 T,请在 S 中找出包含 T 所有字母的最小子串。(minimum-window-substring) 输入: S ="ADOBECODEBANC", T ="ABC"输出:"BANC" 对于这个问题我们常见的思路就是进行匹配 for(int i...
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/字符串的子元素问题,它可以将嵌套的循环问题,转换为单循环问题,降低时间复杂度。 假设有数组[a b c d e f g h]一个大...
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...
本文会将 LeetCode 里面的大部分滑动窗口问题分析、总结、分类,并提供一个可以参考的模版,相信可以有效减少面试当中的算法实现部分的不确定性。 题目概览 滑动窗口这类问题一般需要用到双指针来进行...[LeetCode]Sliding Window Algorithm相关题目总结【重要】 438. Find All Anagrams in a String Given a string ...
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...
In the sliding window technique, we maintain a window that satisfies the problem constraints. The window is unstable if it violates the problem constraints, and it tries to stabilize by increasing or decreasing its size. Following are some of the commonly asked interview questions that use the sl...

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 ) average of two elemen...
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...
今天是算法数据结构专题的第2篇文章,我们一起来学习一下「滑动窗口算法」。 前言 最近刷到leetCode里面的一道算法题,里面有涉及到Sliding windowing算法,因此写一篇文章稍微总结一下 算法题介绍 没有重复字符的子字符的最大长度:给一个字符串,获得没有重复字符的最长子
