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,…
The key condition r - l > k + max is used to determine when the window is too large to meet the problem's requirement. This condition checks whether the number of characters in the current window (r - l) minus the number of occurrences of the most frequent character (max) exceeds k...
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/...

Can you solve this real interview question? Sliding Window Maximum - You are given an array of integers nums, there is a sliding window of size k which is moving from the very left of the array to the very right. You can only see the k numbers in the win
given a fixed length K of a sliding window. so we are given an array as well. and this sliding window slides all the way, and get the maximum each time it moves. return the results in array. my idea: wow, it looks like a deque and priority queue problem! and I remember the imple...
Problem: https://leetcode.com/problems/sliding-window-maximum/ Given an array nums, there is a sliding window of size k which is moving from the very left of the array to the very right. You can only see the k numbers in the window. Each time the sliding window moves right by one ...
