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. 初步构想:处理的对象是Sorted List,既然是已经排好序的链表,所以需要做的就是逐个比较,先将首元素加入到结果链表,然后遍...
leetcode 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. # Definition for singly-linked list. # class ListNode(object): #...
本题类似于 LeetCode 82. Remove Duplicates from Sorted List II, 解题思路同 LeetCode: 82. Remove Duplicates from Sorted List II。只需要将删除当前节点的代码注释掉即可。 AC 代码 AI检测代码解析 /** * Definition for singly-linked list. * struct ListNode { * int v...
203. Remove Linked List Elements Given theheadof a linked list and an integerval, remove all the nodes of the linked list that hasNode.val == val, and returnthe new head. Example 1: Input:head = [1,2,6,3,4,5,6], val = 6Output:[1,2,3,4,5]...
83. Remove Duplicates from Sorted List[值得review] Given a sorted linked list, delete all duplicates such that each element appear only once. For example, Given 1->1->2, return 1->2. Given 1->1->2->3->3, return 1->2->3.
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。
82. Remove Duplicates from Sorted List II Given a sorted linked list, delete all nodes that have duplicate numbers, leaving onlydistinctnumbers from the original list. Example 1: Input:1->2->3->3->4->4->5Output:1->2->5 Example 2: ...
例如输入链表为1->1->2,返回1->2 这题和leetcode26相似,只是数据结构从数组变成了链表 /** * @author rale * * Given a sorted linked list, delete all duplicates such that each element appear only once. * For example, * Given 1->1->2, return 1->2. ...
