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.
/**
* Definition for singly-linked list.
* public class ListNode {
* int val;
* ListNode next;
* ListNode(int x) { val = x; }
* }
*/
public class Solution {
public ListNode deleteDuplicates(ListNode head) {
ListNode p=head; //这样是跟着动的
while(p!=null){
while(p!=null && p.next!=null && p.val==p.next.val){
p.next=p.next.next;
}
p=p.next;
}
return head;
}
}
