基本数学知识

官网上有这么一段描述:
An extensible application is one that you can extend without modifying its original code base. You can enhance its functionality with new plug-ins or modules. Developers, software vendors, and customers can add new functionality or application programming interfaces (APIs) by adding a new Java Archive (JAR) file onto the application class path or into an application-specific extension directory.大致翻译一下就是动态扩展的意思了—-🐂🍺就完了,翻译啥翻译。

前不久看到十大经典排序的动画,感觉挺震撼的,巴拉巴拉老东西写点东西。链接在此 经典排序算法动画

相关大O的复杂度之前记载过,这里也忘记个差不多了。算法空间复杂度和时间复杂度
晚些增加对算法的理解,会比较有趣。
