Linked List Cycle

问题：判断链表是否有环。 分析：利用快慢指针slow,fast          slow指针每次走一步，fast指针每次走两步，倘若存在环，则slow和fast必定在某一时刻相遇。          由于fast指针走的比slow快所以循环的时候只需要判断fast和fast->next不为空，判断fast->next是因为防止出现fast->NULL->next这种情况 /** * Definition for singly-linked list. * struct ListNode { *

题意：天干地支。         天干： Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren and Gui         地支： Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai         每一轮是60次，不要误认为120次。。。（常识），这道题是经典的水题，很水但是还是被坑了很久大概一下午加一晚上。。。。。搞不懂自己什么水平 说下这道题目的坑把，首先是输出地支的时候是小写。。。其次还有AD

【leetcode】Linked List Cycle

这个问题是见的非常多的题目，问题本身而言，技巧性非常强，或者说思路非常巧妙，这里要说的不是这个题目本身。而是说这样的技巧。在非常多的地方是用的到的，比方，在寻找单链表的中间节点的时候，就能够用这样的形式，一个走两步，一个走一步的形式，来获得中间节点。

Leetcode: Linked List Cycle II

题目： Given a linked list, return the node where the cycle begins. If there is no cycle, return null. 思路分析： 和《Leetcode: Linked List Cycle 》一样还是双指针的方法。 ?

Cycle-to-cycle jitter 和 Peak-to-peak jitter什么区别？

相邻周期抖动 相邻周期抖动（Cycle-to-cycle jitter），顾名思义，指的是相邻的两个时钟周期之间的周期长度差异，如下图所示。

LeetCode 141 Linked List Cycle

方法很简单，遍历一遍即可，在遍历过的节点，都改变它的一个状态。如果形成环，会再次指向遍历过的节点，这个时候判断它的状态是否改变。

Linked List Cycle

Problem Given a linked list, determine if it has a cycle in it.

Linked List Cycle

Linked List Cycle Given a linked list, determine if it has a cycle in it. To represent a cycle in the given linked list, we use an integer pos which represents the position (0 If pos is -1, then there is no cycle in the linked list. Example 1: Input: head = [3,2,0,-4], pos = 1 Output: true Explanation: There is a cycle in the linked

Linked List Cycle II

Given a linked list, return the node where the cycle begins. If there is no cycle, return null.

Linked List Cycle II

Linked List Cycle II 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 If pos is -1, then there is no cycle in the linked list. Note: Do not modify the linked list. Example 3: Input: head = [1], pos = -1 Output: no cycle Explanation: There is no cycle in the linked
