数据结构-图(邻接矩阵实现)

作者:互联网

一、图的邻接矩阵实现


1.实现了以顶点数组、邻接矩阵为存储结构的图;

2.实现了图的创建(包含有向/无向图、有向/无向网)、顶点/边的增删操作、深度/广度优先遍历的算法;

3.采用顶点对象列表、边(弧)对象列表的方式,对图的创建进行初始化;引用 "ObjArrayList.h"头文件,头文件可参看之前博文“数据结构之顺序列表(支持对象元素)”代码;

4.采用将顶点数组空位的下标索引入队列的方式,解决顶点在数组(静态)中因增删操作造成的不连续存储的问题;引用 “LinkQueue.h”头文件,头文件可参看之前博文“数据结构之队列(循环队列、链队列的类模板实现)”代码;

5.深度优先遍历采用递归算法;广度优先遍历采用队列方式实现;

6.测试代码中以有向网的所有带权边作为边的初始化数据,选择图类型(DG, UDG, DN, UDN)可创建成不同类型的图。
 

二、测试代码中的图结构图

深度优先遍历序列(从 v1 顶点开始):

1.无向图/网:v1-v2-v3-v5-v4-v6-v7

2.有向图/网:v1-v2-v5-v3-v4-v6-v7

广度优先遍历序列(从 v2 顶点开始):

1.无向图/网:v2-v1-v3-v5-v4-v6-v7

2.有向图/网:v2-v5 后序无法遍历

注:有向图的遍历 是遵循出度方向遍历的,若无出度方向,则遍历终止。
