采用Kruskal算法求最小生成树主要数据结构
edgeset GE 存放图中的所有边
int n,int e 存放图中的顶点数与边数
edgeset C 存放生成树中的边
vexlist gv 图中结点的顶点值
adjmatrix s 用来处理图中结点的查找与合并
int m1,m2 一条边上两顶点所属集合的序号
int k 最小生成树中的边数
int d //图中待扫描边元素的下标(For the Minimum Spanning Tree by Kruskal main data structures edgeset GE store all edges in the figure int n, int e store graph vertices and edges edgeset C storage spanning tree edges in the vexlist gv graph node vertex values adjmatrix s used to process graph node to find and merge int m1, m2 an edge belongs to the set number two vertices int k minimum spanning tree edges int d // figure to be Scan edge element subscript)
