Algorithms & Data structures in C++.
Algorithms & Data Structures in C++
目标 ( goal ) :
- 经典的算法实现
(classical algorithms implementations) - 服务器端
(based on linux/gcc) - 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 ):
- 一个算法用一个.h文件表示放到include下. ( one .header file per algorithm. )
- 算法演示的demo程序放到src下. ( one demo per algorithm. )
- 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!)
- TAB = 4 space. set ts=4 in vim
- Graph的输出格式为 Graphviz Dot格式.
(the output format of the graph is in dot of graphviz.)
eg:
