刚一拿到这道题把他想的太复杂了
明明是长度最大为十的顺序结构就能解决的问题,竟然优先想到用链表。
BFS牵扯到一个队列的操作,在这种小规模数据里面 用顺序结构好很多
题目如下:
For a given undirected graph with N vertices and E edges, please list all the connected...

Given a connected undirected graph, tell if its minimum spanning tree is unique.
Definition 1 (Spanning Tree): Consider a connected, undirected graph G = (V, E). A spanning tree of G is a subgraph of G, say T = (V', E'), with the following properties:
1...

有关基本图论定义与术语的知识老是记不清楚,这里做一个归纳:
图与网络(Graph and Network):
二元组(V,E)称为图(graph)。V为结点(node)或顶点(vertex)集。E为V中结点之间的边的集合。
点对(u,v)称为边(edge)或称弧(arc),其中u,v属于V,称u,v是相邻的(adjacent),称u,v,与边(u,v)相关联(incident) 或相邻。...
