Remove all elements from a linked list of integers that have value val.
Example Given: 1 --& 2 --& 6 --& 3 --& 4 --& 5 --& 6, val = 6 Return: 1 --& 2 --& 3 --& 4 --& 5
Credits: Special thanks to @mithmatt for adding this problem and creating all test cases.
ListNode* removeElements(ListNode* head, int val) {
ListNode* currNode =
while (true) {
if (head == NULL) return NULL;
if (currNode-&val != val)
currNode = currNode-&
head = currN
while (currNode-&next) {
if (currNode-&next-&val == val) {
currNode-&next = currNode-&next-&
currNode = currNode-&

Linked List Basics
Stanford CS Education Library: a 26 page& introduction to linked lists
in C/C++. Includes examples, drawings, and practice problems, and solution
code. The more advanced article,& , has 18 sample problems with solutions.
This article introduces the basic structures and techniques for building
linked lists with a mixture of explanations, drawings, sample code, and
exercises. The material is useful if you want to understand linked lists
or if you want to see a realistic, applied example of pointer-intensive
code. Even if you never really need a linked list, they are an excellent
way to learn pointers and pointer algorithms.

Write a function to delete a node (except the tail) in a singly linked list, given only access to that node.
Supposed the linked list is&1 -& 2 -& 3 -& 4&and you are given the third node
with value&3, the linked list should become&1
-& 2 -& 4&after calling your function.
给定链表中的一个节点，删除该节点。
正常情况下链表中节点的删除是需要知道被删除节点的前一个节点的，将它前一个节点的next指针指向它的下一个节点，这个节点就从链表中删除了。但是这里没有提供前一个节点，而是提供了当前节点。
一个技巧就是用它的下一个节点的值覆盖当前节点的值，然后将下一个节点删除掉，这样就等效删除了当前节点。但是需要注意这种方法不能删除尾节点（题目中也给出了这个条件）。
runtime:16ms
* Definition for singly-linked list.
* struct ListNode {
ListNode *
ListNode(int x) : val(x), next(NULL) {}
class Solution {
void deleteNode(ListNode* node) {
node-&val=node-&next-&
node-&next=node-&next-&
};上面两行代码等效于下面这一行代码：
*node=*node-&
直接使用ListNode默认的赋值操作符。
