今天扣丁学堂Python培训老师给大家介绍一下关于Python3实现的判断环形链表算法,涉及Python针对环形链表的遍历、判断相关操作技巧详解,希望对学习Pyythn开发的同学有所帮助,下面我们一起来看一下吧。
# Definition for singly-linked list. # class ListNode(object): # def __init__(self, x): # self.val = x # self.next = None class Solution(object): def hasCycle(self, head): """ :type head: ListNode :rtype: bool """ slow = fast = head while fast and fast.next: slow = slow.next fast = fast.next.next if fast == slow: return True return False
# Definition for singly-linked list. # class ListNode(object): # def __init__(self, x): # self.val = x # self.next = None class Solution(object): def hasCycle(self, head): """ :type head: ListNode :rtype: bool """ if not head: return False cur = head.next while cur: if cur.next == head: return True cur = cur.next return False
