Keith Schwarz是一个斯坦福大学计算机科学系的讲师。他对编程充满了热情。他的主页上他自己正在实现各种各样的有意思的算法和数据结构，http://www.keithschwarz.com/interesting/， 目前这个网页上有88个（见下面的列表），但这位大哥要干135个，你可以看看他的To-Do List。

从这个列表上，我们可以看到，他从去年7月份就在自己实现这些东西了，我把他实现的这些算法转过来，

一方面我们可以学习一下这些算法和代码，因为很多东西对我来说都比较新，我以前列举过一些经典的算法，算法和数据结构词典，还有可视化的数据结构和算法， 不过感觉都没有这个全。

另一方面我希望这个事可以影响到一些正在学习编程的人。看看别人是怎么学习编程的，希望对你有借鉴作用。
