1. interactive python 4.3 recursion:  https://www.youtube.com/watch?v=ygK0YON10sQ this video is really good.

又看了一遍怎么刷题的贴：
找来PIC从头到尾skim了一遍，发现不用java看这些书还真是很占劣势。
又在coursera卡了一下greedy algo。
看leet code two sum那道题，Java用hashmap做，就想复习一遍hashmap。
据说这个人的文章很好： http://blog.csdn.net/u011095253/article/details/9158387

考你一题：
hashmap和binary tree的区别和用处在哪里？嘻嘻。

10/16 went through tree structure on interactive python

哈哈，一转眼就两年了，今年春天换了工作就倦怠了。新年快到啦，这个楼我继续盖起来！今天写了TwoSum，三遍才过。。。
