floyd cycle detection 都是采用一快一慢两个指针,快的一次向前移动两步,慢的一次向前移动一步,这样快的每次都会多领先慢的一步。如果有环那么慢和快一定会相遇。 第一次是在链表的tag里遇到的:141.Linked List Cycle 要求判断是否有环 以及142. Linked List Cycle II 要求在判断是否有环,并在有环的情况下...
leetcode: 141. Linked List Cycle Difficulty Easy. Problem AC...[leetcode]141. Linked List Cycle Given a linked list, determine if it has a cycle in it. 分析: 判断一个链表是否存在环。设置快慢指针,慢指针一次走一步,快指针一次走两步,如果最后快指针能够追上慢指针,则该链表存在环。 ......
