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.
含义：从已经排好序的列表中，删除重复值节点
1 public ListNode deleteDuplicates(ListNode head) { 2 ListNode curNode=head; 3 while (curNode != null && curNode.next != null) 4 { 5 if (curNode.val == curNode.next.val) 6 { 7 curNode.next = curNode.next.next; 8 }else 9 { 10 curNode = curNode.next; 11 } 12 } 13 return head; 14 }
