https://leetcode.com/problems/remove-duplicates-from-sorted-list/
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.
题意分析
Input:
:type head: ListNode
Output:
:rtype: ListNode
Conditions:一个有序list，删除掉重复的元素
题目思路
每次判断增加一个节点时，看是否与当前结点重复，重复则跳过
AC代码（Python）
1 # Definition for singly-linked list. 2 # class ListNode(object): 3 # def __init__(self, x): 4 # self.val = x 5 # self.next = None 6 7 class Solution(object): 8 def deleteDuplicates(self, head): 9 """ 10 :type head: ListNode 11 :rtype: ListNode 12 """ 13 if head == None or head.next == None: 14 return head 15 p = head 16 while p.next != None: 17 if p.val == p.next.val: 18 p.next = p.next.next 19 else: 20 p = p.next 21 return head 22
