2023-10-23 03:10:12 +08:00
< p > 以下是邻接表的代码实现。对比图 9-8 ,实际代码有以下不同。< / p >
< ul >
< li > 为了方便添加与删除顶点,以及简化代码,我们使用列表(动态数组)来代替链表。< / li >
< li > 使用哈希表来存储邻接表,< code > key< / code > 为顶点实例,< code > value< / code > 为该顶点的邻接顶点列表(链表)。< / li >
< / ul >
2023-10-23 04:56:26 +08:00
< p > 另外,我们在邻接表中使用 < code > Vertex< / code > 类来表示顶点,这样做的原因是:如果与邻接矩阵一样,用列表索引来区分不同顶点,那么假设要删除索引为 < span class = "arithmatex" > \(i\)< / span > 的顶点,则需遍历整个邻接表,将所有大于 < span class = "arithmatex" > \(i\)< / span > 的索引全部减 < span class = "arithmatex" > \(1\)< / span > ,效率很低。而如果每个顶点都是唯一的 < code > Vertex< / code > 实例,删除某一顶点之后就无须改动其他顶点了。< / p >

< p > 观察表 9-2 ,似乎邻接表(哈希表)的时间效率与空间效率最优。但实际上,在邻接矩阵中操作边的效率更高,只需一次数组访问或赋值操作即可。综合来看,邻接矩阵体现了“以空间换时间”的原则,而邻接表体现了“以时间换空间”的原则。< / p >
