题解
只需在83题基础上加一个while循环即可
class Solution {public ListNode deleteDuplicates(ListNode head) {ListNode dummy = new ListNode(101, head);ListNode cur = dummy;while (cur.next != null && cur.next.next != null) {int val = cur.next.val;if (cur.next.next.val == val) {while (cur.next != null && cur.next.val == val) {cur.next = cur.next.next;}} else {cur = cur.next;}}return dummy.next;}
}
