这是悦乐书的第296次更新,第315篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第164题(顺位题号是703).设计一个类来查找流中第k个最大元素.请注意,它是排序顺序中的第k个最大元素,而不是第k个不同元素.KthLargest类有一个构造方法,此构造方法有一个整数k和一个整数数组nums两个参数,它包含来自流的初始元素.对于方法KthLargest.add的每次调用,返回表示流中第k个最大元素的元素.例如: int k = 3; int [] arr = [4…

设计一个找到数据流中第K大元素的类(class).注意是排序后的第K大元素,不是第K个不同的元素. 你的 KthLargest 类需要一个同时接收整数 k 和整数数组nums 的构造器,它包含数据流中的初始元素.每次调用 KthLargest.add,返回当前数据流中第K大的元素. 示例: int k = 3; int[] arr = [4,5,8,2]; KthLargest kthLargest = new KthLargest(3, arr); kthLargest.add(3);   /…

害,别误会,我这里说的stream不是流式编程,不是大数据处理框架.我这里说的是stream指的是jdk中的一个开发工具包stream. 该工具包在jdk8中出现,可以说已经是冷饭了,为何还要你说?只因各家一言,不算得自家理解,如若有空,何多听一版又何妨. 本篇主要从几个方面讲讲:1. 我们常见的stream都有哪些? 2. stream包有哪些好处? 3. stream包的实现原理? 相信这些多少会解开大家的一些迷惑. 1. 我们常见的stream都有哪些? stream直接翻译为流.何谓流?…

拦截器(Interceptor)是CXF功能最主要的扩展点,可以在不对核心模块进行修改的情况下,动态添加很多功能.拦截器和JAX-WS Handler.Filter的功能类似,当服务被调用时,就会创建一个拦截器链(Interceptor Chain),拦截器链在服务输入(IN)或输出(OUT)阶段实现附加功能. 拦截器可以在客户端,也可以在服务端添加.当客户端发起一个WebService请求时,在客户端会创建输出拦截器链,服务端接收到客户端的后,会创建输入拦截器链.当服务端返回响应消息时,响应消…
