邻接链表(Adjacency List)是图的一种链式存储结构,与树型结构中的孩子链表相似。通常邻接链表也称邻接表。 1. 邻接表的结点结构 边结点结构 邻接表中每个表结点均有两个域: ① 邻接点域adjvex 存放与vi相邻接的顶点vj的序号j。 ② 链域next 将邻接表的所有表结点链在一起。 注意: 如果带权图,则在表...

Given a directed graph represented as an adjacency list, return its reverse so if an edge goes from A to B, it now goes from B to A. Each list in the adjacency list should be sorted in ascending order. Example 1 Input 1 2

In an adjacency list, each node stores a list of its neighboring nodes, along with the edge properties. In an adjacency matrix, the rows and columns represent nodes, and the matrix cells indicate whether there is a relationship between nodes and may contain edge properties. Querying: Graph dat...
