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...

5.2.4.5 Remove Linked List Elements 一、题目 Remove all elements from a linked list of integers that have valueval. Example Given1->2->3->3->4->5->3, val = 3, you should return the list as1->2->4->5 删除链表中等于给定值val的所有节点。
Remove Linked List Elements 思路:没啥好说的,断链操作。 主要是val在第一个元素的时候考虑,快慢指针的条件是while p and p.next这个条件不错。 这个逻辑还是比较凌乱,要是指示一个prev、一个dummy.next 会更好。 判断链表中是否有环存在 /** * Definition for singly-linked list. * class ListNode { *...
Write a C program that removes elements with even indices from a singly linked list. Sample Solution:C Code:#include<stdio.h> #include <stdlib.h> // Definition for singly-linked list. struct Node { int data; struct Node* next; }; // Function to remove elements with even indices from ...
