删除排序链表中重复的节点 递归方式

思路比较简单，直接看代码

/* public class ListNode {    int val;    ListNode next = null;    ListNode(int val) {        this.val = val;    }}*/public class Solution {    public ListNode deleteDuplication(ListNode pHead)    {if(pHead == null||pHead.next == null)            return pHead;        if(pHead.val == pHead.next.val){//第一个节点是重复节点，则跳过重复节点            ListNode node = pHead.next;            while(node != null&&node.val == pHead.val)                node = node.next;            return deleteDuplication(node);        }else{            //第一个节点不是重复节点            pHead.next = deleteDuplication(pHead.next);            return pHead;        }    }}
