Can you solve this real interview question? Remove Linked List Elements - Given the head of a linked list and an integer val, remove all the nodes of the linked list that has Node.val == val, and return the new head. Example 1: [https://assets.leetc

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...
2、虚拟头节点的“秒”用,不需要对第一个元素做特殊处理,避免边界条件考虑不周全 最终AC的代码如下: # Definition for singly-linked list.# class ListNode:# def __init__(self, x):# self.val = x# self.next = NoneclassSolution:defremoveElements(self,head,val):""" ...
LeetCode 203 [Remove Linked List Elements] 原题 删除链表中等于给定值val的所有节点。 样例 给出链表 1->2->3->3->4->5->3, 和 val = 3, 你需要返回删除3之后的链表:1->2->4->5。 解题思路 最基础的链表操作,由于第一个节点可能被删除,所以借助Dummy Node 完整代码......
