-100 <= Node.val <= 100 The list is guaranteed to be sorted in ascending order. 和之前那道Remove Duplicates from Sorted List不同的地方是这里要删掉所有的重复项,由于链表开头可能会有重复项,被删掉的话头指针会改变,而最终却还需要返回链表的头指针。所以需要定义一个新的节点,然后链上原链表,然后定义...
LeetCode: 82. Remove Duplicates from Sorted List II 题目描述 Given a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list. For example, Given 1->2->3->3->4->4->5, return 1->2->5...
Given theheadof a linked list, find all the values that appear more than once in the list and delete the nodes that have any of those values. Returnthe linked list after the deletions. Example 1: Input: head = [1,2,3,2] Output: [1,3] Explanation: 2 appears twice in the linked ...

https://leetcode.com/problems/remove-linked-list-elements 和常规的删除一个node的情况不同的是,它要求删除所有val为指定值的node。 这道题要注意一个点: head node 的值是指定值,和中间node的值为指定值,在操作上不一样。比较好的办法是,在head前创建一个dummy node,那么这两种情况的操作就一样,最后返回...
83. Remove Duplicates from Sorted List Given a sorted linked list, delete all duplicates such that each element appear onlyonce. For example, Given1->1->2, return1->2. Given1->1->2->3->3, return1->2->3. 题目大意: 去除有序链表内部相同元素,即相同元素只保留一个。
