Return true if there is a cycle in the linked list. Otherwise, return false. 英文版地址 leetcode.com/problems/l 中文版描述 给你一个链表的头节点 head ,判断链表中是否有环。如果链表中有某个节点,可以通过连续跟踪 next 指针再次到达,则链表中存在环。 为了表示给定链表中
There is a cycle in a linked list if there is some node in the list that can be reached again by continuously following thenextpointer. Internally,posis used to denote the index of the node that tail'snextpointer is connected to.Note thatposis not passed as a parameter. Returntrueif ther...
Given a linked list, determine if it has a cycle in it. Problem II: Given a linked list, return the node where the cycle begins, if there is no cycle, return null. Follow up: Can you solve it without using extra space? 分析: 第一个问题要求检测链表中是否有环路。解决思路很直观,用快...
To represent a cycle in the given linked list, we use an integer pos which represents the position (0-indexed) in the linked list where tail connects to. If pos is -1, then there is no cycle in the linked list. 翻译过来就是找到链表中的环,并返回环起点的节点。
Given a linked list, return the node where the cycle begins. If there is no cycle, return null. To represent a cycle in the given linked list, we use an integer pos which represents the position (0-indexed) in the linked list where tail connects to. If pos is -1, then there is ...

Congratulations. I posted about your journey earlier in the trip. Please tell me how the bicyclist navigates. Can you steer or do you follow a pre-programmed path? Are the pedals linked to the video so the scenery going by matches your speed?
Explanation: There is a cycle in the linked list, where the tail connects to the 1st node (0-indexed). 分析: 在题设部分已经阐述pos是与本题毫无关系的,所以,主要是围绕链表进行的思考的。 示例代码: public class Solution { public boolean hasCycle(ListNode head) { ...
