Given a sorted linked list, delete all duplicates such that each element appear only once.
Example 1:
Input: 1->1->2
Output: 1->2
Example 2:
Input: 1->1->2->3->3
Output: 1->2->3
题意:
有序链表去重
思路:
代码:
1 class Solution {
2 public ListNode deleteDuplicates(ListNode head) {
3 if(head ==
null)
return head;
4 ListNode cur =
head;
5 while(cur.next !=
null){
6 if(cur.val ==
cur.next.val){
7 cur.next =
cur.next.next;
8 }
else{
9 cur =
cur.next;
10 }
11 }
12 return head;
13 }
14 }
