If there are multiple suitable places for insertion, you may choose any place to insert the new value. After the insertion, the circular list should remain sorted. If the list is empty (i.e., given node isnull), you should create a new single circular list and return the reference to ...

力扣leetcode.cn/problems/insert-into-a-sorted-circular-linked-list/ 首先考虑边界情况。当链表为空时,新建节点并返回该节点即可。 接下来是一般情况。对于插入的数值insertVal,有以下几种可能: 1、其数值位于两个相邻的节点now和prev之间,即 prev.val <= insertVal <= now.val 这种情况下,应该将其插入...

The figure below shows the circular doubly linked list for the BST above. The "head" symbol means the node it points to is the smallest element of the linked list. 我们希望将这个二叉搜索树转化为双向循环链表。链表中的每个节点都有一个前驱和后继指针。对于双向循环链表,第一个节点的前驱是最后一...
