那么就应该 suppose 返回来的链表就已经没有重复项了,此时接到 head 结点后面,在第三句的时候再来检查一下 head 是否又 duplicate 了,实际上递归一直走到了末尾结点,再不断的回溯回来,进行删除重复结点,参见代码如下:
Given a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list. Example 1: Input: 1->2->3->3->4->4->5 Output: 1->2->5 1. 2. Example 2: Input: 1->1->1->2->3 Output: 2->3 1. 2. 题目大意 删除链表中重复的...
