Bubble sort,It's a relatively basic algorithm.The core implementation ideas are as follows: 1.Define an array,The length is N. 2.Compares each pair of adjacent items and swaps them if they are in the wrong order. such as: if (a[j - 1] > a[j]) {//The…
w非全尺寸分组的发送条件 HTTP The Definitive Guide TCP has a data stream interface that permits applications to stream data of any size to the TCP stack—even a single byte at a time! But because each TCP segment carries at least 40 bytes of flags and headers, ne…

一.前言 本篇是在分析Executors源码时,发现JUC集合框架中的一个重要类没有分析,SynchronousQueue,该类在线程池中的作用是非常明显的,所以很有必要单独拿出来分析一番,这对于之后理解线程池有很有好处,SynchronousQueue是一种阻塞队列,其中每个插入操作必须等待另一个线程的对应移除操作 ,反之亦然.同步队列没有任何内部容量,甚至连一个队列的容量都没有. 二.SynchronousQueue数据结构 由于SynchronousQueue的支持公平策略和非公平策略,所…

Welcome back. This time we’re actually gonna see triangles being rasterized – finally! But before we can rasterize triangles, we need to do triangle setup, and before I can discuss triangle setup, I need to explain what we’re setting things up for; i…

最近在刷 fcc的题,跟升级打怪一样,一关一关的过,还挺吸引我的.今天抽时间把 Basic Algorithm Scritping  这部分题做了,根据一些提示,还是比较简单的.有些题的处理方式 方法,我想值得借鉴.比如在项目中有时候要处理一个字符,如果想不到一些相关的方法,还挺费事的,所以,在此记录下来,如果以后遇到一些字符或者数组处理,可以来翻翻这篇文章,希望以此得到一些提示而不是去翻文档.   看到此博文的博友,有更好更简单的代码或者好的想法,请留言交流(我一直觉得只有学习别人的优秀代码才…
