1.删除链表中的节点https://leetcode-cn.com/problems/delete-node-in-a-linked-list/

一开始没看清题目中传入的参数为“要被删除的节点”，找了半天链表在哪

class ListNode:
    def __init__(self, x):
        self.val = x
        self.next = None

class Solution:
    def deleteNode(self, node):
        """
        :type node: ListNode
        :rtype: void Do not return anything, modify node in-place instead.
        """
        node.val = node.next.val
        node.next = node.next.next
