今天和大家聊的问题叫做将二叉搜索树转化为排序的双向链表,我们先来看题面:https://leetcode-cn.com/problems/convert-binary-search-tree-to-sorted-doubly-linked-list/ Convert a BST to a sorted circular doubly-linked list in-place. Think of the left and right pointers as synonymous ...
您将获得一个双向链表,除了下一个和前一个指针之外,它还有一个子指针,可能指向单独的双向链表。这些子列表可能有一个或多个自己的子项,依此类推,生成多级数据结构,如下面的示例所示。 You are given a doubly linked list which in addition to the next and previous pointers, it could have a child pointer...
