【138】Copy List with Random Pointer(2018年12月1日,第一次复习) 复制含有随机指针结点的链表。一种特殊的链表结点类描述如下: //Definition for singly-linked list with a random pointer.structRandomListNode {intlabel; RandomListNode*next, *random; RandomListNode(intx) : label(x), next(NULL), rand...
You are given a doubly linked list which in addition to the next and previous pointers, it could have a child pointer, which may or may not point to a separate doubly linked list. These child lists may have one or more children of their own, and so on, to produce a multilevel data ...
