Solution:Basically, you would have a loop that traverse the cyclic sorted list and find the point where you insert the value (Let ...
看起来很难,但是仔细想一下,实质就是二叉树的中序遍历的问题,中序遍历有递归和非递归(至少两种写法)。 递归: 非递归 Divide a ...
Reverse a linked list from position m to n. Do it in-place and in one-pass. For example:Given 1->2->3->4->5->NULL, m = 2 and n ...
1. 链表 数组是一种顺序表,index与value之间是一种顺序映射,以\(O(1)\)的复杂度访问数据元素。但是,若要在表的中间部分插入(或删除)某一个元素时,需要将后续的数据元素进行移动,复杂度大概为\(O(n)\)。链表(Linked List)是一种链式表,克服了上述的缺点,插入和删除 ...
原题地址:http://oj.leetcode.com/problems/linked-list-cycle/ 题意:判断链表中是否存在环路。 解题思路:快慢指针技巧,slow指针和fast指针开始同时指向头结点head,fast每次走两步,slow每次走一步。如果链表不存在环,那么fast ...
比I麻烦点的就是找到循环开始点TAT I只是判断是否循环。要求不使用额外空间(不然hash就可以了 按I的思路,我们又慢指针S和快指针F。。。F走两步,S走一步。。。若有环,必定相遇。 画个图( ...
