对图的各种操作，包括深度遍历，广度遍历，最小生成树，最短路径的各中算法，而且有递归和非递归方式，对学习数据结构有很大的帮助。

代码全是自己根据理解自己写的，思路很符合初学者。-Various operations on the map, including the traverse depth, breadth traversal, minimum spanning tree, shortest path in the algorithm, and recursive and non recursive way, great help for learning data structures. Code all their own understanding of their own to write, the idea is consistent with the beginners.
