Web思路：我们使用快慢指针的方法，让fast指针一次走两步，slow指针一次走一步，当链表有环的时候，当slow进入环了，fast就开始追slow，假设fast跟slow的距离为N，每走一次fast跟slow的距离就会缩小一步，也就是N-1，N-2，N-3，N-4，直到N为0 fast就追上slow了！ WebListNode *pre = head; ListNode *cur = head; And the opening brace belongs in column 0 (I guess you don't agree, but there are - or were anyway - tools that rely on this). An alternative implementation might use a function to find the number of entries in the list and another to return a specified entry (size - n - 1, in this case).
