Algorithms & Data structures in C++.

Algorithms & Data Structures in C++

目标 ( goal ) :

1. 经典的算法实现
   (classical algorithms implementations)
2. 服务器端
   (based on linux/gcc)
3. 正确，易于使用和改造, 一个头文件一个算法，并附带一个demo.
   (correct! and ease of use, one .header file per algorithm)

约定 ( Convention ):

1. 一个算法用一个.h文件表示放到include下. ( one .header file per algorithm. )
2. 算法演示的demo程序放到src下. ( one demo per algorithm. )
3. 程序正确通过后，请发起Pull Requests，代码被验证后入库，并在README中发布新算法实现。 (Please Use Fork+Pull Requests !!! Correctness is the most important!)
4. TAB = 4 space. set ts=4 in vim
5. Graph的输出格式为 Graphviz Dot格式. (the output format of the graph is in dot of graphviz.) eg:
