LeedCode 之 Remove Duplicates from Sorted List

题目链接：Remove Duplicates from Sorted List
和之前写过的题有点类似，直接上代码。

/**
 * 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) {
        if(head==null||head.next==null)
            return head;
        ListNode point = head;
        ListNode move = point.next;
        while(move!= null){
            if(point.val == move.val)
                {
                move = move.next;
                point.next = move;
                }
            else
            {
                move = move.next;
                point = point.next;
            }
        }
        return head;
    }
}
