A linked list is given such that each node contains an additional random pointer which could point to any node in the list or null. Return a deep copy of the list. 这题感觉像是Clone Graph的简化版(相邻节点个数最多为2个),不知道是不是理解有误,总之使用以上的思路是可以通过的。唯一区别是要...
Clone an undirected graph. Each node in the graph contains alabeland a list of itsneighbors. OJ's undirected graph serialization: Nodes are labeled uniquely. We use#as a separator for each node, and,as a separator for node label and each neighbor of the node. As an example, consider the...
