简历window的char to count map 使用一个count变量来计算window中后多少个char符合要求 class Solution(object): def findAnagrams(self, s, p): """ :type s: str :type p: str :rtype: List[int] """ charFreq = {} # target charFreq Map for c in p: charFreq[c] = charFreq.get(c, 0...
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 position. Your job is to output the median array for each win...
Among all leetcode questions, I find that there are at least 5 substring search problem which could be solved by the sliding window algorithm. template: publicclassSolution {publicList<Integer>slidingWindowTemplateByHarryChaoyangHe(String s, String t) {//init a collection or int value to save ...
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...

一、窗口(window) (1)一般真实的流都是无界的,怎样处理无界的数据? (2)可以把无限的数据流进行切分,得到有限的数据集进行处理——也就是得到有界流; (3)窗口(window)就是将无限流切割为有限流的一种方式,它会将流数据分发到有限大小的桶(bucket)中进行分析; 二、window类型(1)时间窗口(Time Window):滚动时...

In this paper we present a novel streaming algorithm for the k-center clustering problem for general metric spaces under the sliding window model. The algorithm maintains a small coreset which, at any time, allows to compute a solution to the k-center problem on the current window with an ap...
