# class ListNode: # def __init__(self, x): # self.val = x # self.next = None # # 代码中的类名、方法名、参数名已经指定,请勿修改,直接返回方法规定的值即可 # # # @param head ListNode类 # @return ListNode类 # class Solution: def deleteDuplicates(self , head: ListNode) -> ListNode: #空链表 if head == None: return None #遍历指针 cur = head #指针当前和下一位不为空 while cur and cur.next: #如果当前与下一位相等则忽略下一位 if(cur.val == cur.next.val): cur.next = cur.next.next #否则指针正常遍历 else: cur = cur.next return head
