这些有趣的代码是我研究和编写有趣的算法和数据结构而积累下来的，在进行这项工作的过程中，我希望能够学习到数学技巧以及提高编程技能。
这些例子是使用多种语言编写的，我通常喜欢使用C++来编写算法，因为STL提供了非常强大的库来描述支持多种数据类型的算法（译者注：也即泛型）。我使用JAVA来编写大部分的数据结构，因为JAVA中集合框架能够与应用程序无缝集成，同时JAVA中的垃圾回收机制简化了资源管理。有时，我发现使用另外一种语言（如Haskell）能够更好的表达一种算法或数据结构，此时，我会放弃通常的编程语言习惯。
如果你很好奇我将来希望实现的算法或数据结构，请查看我的TODO列表。
如果你想在自己的应用程序中使用其中的任何代码，可以直接使用，不需要明确引用这个网站，当然如果你引用了，我也是很乐意的。但是，请不要剽窃这里的代码（通过署自己的名），这样是不诚实的。最后需要提醒的是我非常有信心这里的代码是正确的，当然，我并没有对其进行非常严格的测试，所以可能也会潜伏着一两个错误。
