Given an array nums and a target value k, find the maximum length of a subarray that sums to k. If there isn't one, return 0 instead. Example 1: Given nums = [1, -1, 5, -2, 3], k = 3, return 4. (because the subarray [1, -1, 5, -2] sums to 3 and is th…

Given a string array words, find the maximum value of length(word[i]) * length(word[j]) where the two words do not share common letters. You may assume that each word will contain only lower case letters. If no such two words exist, return 0. Example…

在分布式集群中,对机器的添加删除,或者机器故障后自动脱离集群这些操作是分布式集群管理最基本的功能.如果采用常用的hash(object)%N算 法,那么在有机器添加或者删除后,就需要大范围的移动原有数据,这种大规模的移动数据在大规模的分布式集群中是不可被接受的,因为移动过程中造成的'抖动'或者可能出现的数据读写问题,都会大大降低集群的可用性.谷歌前一段(17年4月)时间对一致性哈希做了简单改进,即对每个节点最大连接数做限制,新来的请求如果发现目标节点达到最大限制,就会顺时针方向寻找下一个连接数没…

Given two integer arrays A and B, return the maximum length of an subarray that appears in both arrays. Example 1: Input: A: [1,2,3,2,1] B: [3,2,1,4,7] Output: 3 Explanation: The repeated subarray with maximum length is [3, 2, 1]. Note: 1 <= len(A),…

一.介绍 哈希(hash)是一种非常快的查找方法,一般情况下查找的时间复杂度为O(1).常用于连接(join)操作,如Oracle中的哈希连接(hash join). InnoDB存储引擎会监控对表上索引的查找,如果观察到建立哈希索引可以带来速度的提升,则建立哈希索引,所以称之为自适应(adaptive)的. 自适应哈希索引通过缓冲池的B+树构造而来,因此建立的速度很快.而且不需要将整个表都建哈希索引,InnoDB存储引擎会自动根据访问的频率 和模式来为某些页建立哈希索引. 二.示例 三.限制…
