Task description A non-empty zero-indexed array A consisting of N integers is given. The leader of this array is the value that occurs in more than half of the elements of A. An equi leader is an index S such that 0 ≤ S < N − 1 and two sequences A[0]…
codility上面添加了教程.目前只有lesson 1,讲复杂度的……里面有几个题, 目前感觉题库的题简单. tasks: Frog-Jmp: 一只青蛙,要从X跳到Y或者大于等于Y的地方,每次跳的距离为D,问至少跳几次. X,Y,D都是[1..10^9]的整数. 要求时间空间复杂度O(1). 这个题比较简单,就是做除法嘛,我们不知道X是否已经不小于Y了,我加了个判断,不过也就一句话. 代码: // you can also use includes, for example: // #incl…
leader的实现类为LeaderZooKeeperServer,它间接继承自标准ZookeeperServer.它规定了请求到达leader时需要经历的路径: PrepRequestProcessor -> ProposalRequestProcessor ->CommitProcessor -> Leader.ToBeAppliedRequestProcessor ->FinalRequestProcessor 具体情况可以参看代码: @Override protected v…

一.前言 前面学习了Zookeeper服务端的相关细节,其中对于集群启动而言,很重要的一部分就是Leader选举,接着就开始深入学习Leader选举. 二.Leader选举 2.1 Leader选举概述 Leader选举是保证分布式数据一致性的关键所在.当Zookeeper集群中的一台服务器出现以下两种情况之一时,需要进入Leader选举. (1) 服务器初始化启动. (2) 服务器运行期间无法和Leader保持连接. 下面就两种情况进行分析讲解. 1. 服务器启动时期的Leader选举 若进行…
1.题目: A game for one player is played on a board consisting of N consecutive squares, numbered from 0 to N − 1. There is a number written on each square. A non-empty zero-indexed array A of N integers contains the numbers written on the squares. More…
How to solve this HARD issue 1. Problem: A non-empty zero-indexed array A consisting of N integers is given. A peak is an array element which is larger than its neighbours. More precisely, it is an index P such that 0 < P < N − 1 and A[P − 1] < A…
要想使用Leader选举功能,需要添加recipes包,可以在maven中添加如下依赖: <dependency> <groupId>org.apache.curator</groupId> <artifactId>curator-recipes</artifactId> <version>2.9.0</version> </dependency> 当然了,由于recipes需要使用framework,所以你肯…
首先上题目: A DNA sequence can be represented as a string consisting of the letters A, C, G and T, which correspond to the types of successive nucleotides in the sequence. Each nucleotide has an impact factor, which is an integer. Nucleotides of types A,…
个人觉得项目leader应该具备一下基础: 1.技术能力 2.领导能力 3.过滤产品不合理需求能力 4.项目周期把控能力…
