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,…

Given an arraynums, there is a sliding window of sizekwhich is moving from the very left of the array to the very right. You can only see theknumbers in the window. Each time the sliding window moves right by one position. For example, Givennums=[1,3,-1,-3,5,3,6,7], andk=...
比如有最经典的sliding window模式,Two pointers模式,快慢指针模式,合并intervals模式,cyclic sort模式,in-place翻转链表模式,树上的BFS,树上的DFS,双Heaps模式,subsets模式,二分法变种,Top K模式,多路模式(K-ways),0/1背包,拓扑排序。 需要的小伙伴就去来一波吧! 他家最最出名的还是这门Grokking the System Desig...

假设说有一个 sliding window,从左慢慢往右划,不断调整左右边界:左边吐出 char,右边吃进 char; 这个window 里面的不同 char 各有多少个,通过一个 map 来记录; 这个window 的左边界所对应的 char 作为所考察的 repeating char,在左边界固定的基础上不断右移右边界,记录 window 的最大值,如果其他 char 的数量...
Back to our problem. We use HashSet to store the characters in current window [i, j) (j = i initially). Then we slide the index j to the right. If it is not in the HashSet, we slide j further. Doing so until s[j] is already in the HashSet. At this point, we found the...

https://leetcode-cn.com/problems/sliding-window-median/ 文章目录 分析 解法 `addNum` `eraseNum` 代码 分析 这道题是295.数据流的中位数这题的进阶版,此时数据流变成了一个固定大小的窗口,每次新加入一个数字就会有一个旧的数字被移除,因此,这相当于在295题的基础上引入了删除操作。 295题的解法是用...
[LeetCode] 480. Sliding Window Median Problem Median is the middle value in an ordered integer list. If the size of the list is even, there is no middle value. So the median is the mean of the two middle value. Examples: [2,3,4] , the median is 3...
