Given a linked list, determine if it has a cycle in it.Follow up:Can you solve it without using extra space?CICT上有差不多的原题， 1. 初始化两个iterator都等于head， 设为a，b。2. 每次迭代，a走一步，b走两步。3. 如果a或者b走到null那就说明链表没有环，返回fa

解题思路：三指针，跟踪算法的步骤例如以下：
代码例如以下：
/**
* Definition for singly-linked list.
* struct ListNode {
* int val;
* ListNode *next;
* ListNode(int x) : val(x), next(NULL) {}
* };
