2.1 Write code to remove duplicates from an unsorted linked list.FOLLOW UPHow would you solve this problem if a temporary buffer is not allowed? 这道题让我们移除无序链表中的重复项,在LeetCode中有两道类似的题是Remove Duplicates from Sorted List 移除有序链表中的重复项 和 Remove Duplicates fr…

2.2 Implement an algorithm to find the kth to last element of a singly linked list. 这道题让我们求链表中倒数第k个元素,LeetCode中相类似的题目有Kth Largest Element in an Array 数组中第k大的数字 和 Kth Smallest Element in a BST 二叉搜索树中的第K小的元素.但那两道题和这题又不一样,首先这道题是要在链表中操作,链表的特点就是不能通过下标来直接访…

2.3 Implement an algorithm to delete a node in the middle of a singly linked list, given only access to that node.EXAMPLEInput: the node c from the linked list a->b->c->d->eResult: nothing is returned, but the new linked list looks like a- >…

2.4 Write code to partition a linked list around a value x, such that all nodes less than x come before all nodes greater than or equal to x. LeetCode上的原题,请参见我之前的博客Partition List 划分链表.…

2.6 Given a circular linked list, implement an algorithm which returns the node at the beginning of the loop.DEFINITIONCircular linked list: A (corrupt) linked list in which a node's next pointer points to an earlier node, so as to make a loop in the…

4.4 Given a binary tree, design an algorithm which creates a linked list of all the nodes at each depth (e.g., if you have a tree with depth D, you'll have D linked lists).…

17.13 Consider a simple node-like data structure called BiNode, which has pointers to two other nodes. The data structure BiNode could be used to represent both a binary tree (where nodel is the left node and node2 is the right node) or a doubly link…

2014-05-03 23:18 题目链接 原题: Insert a element in a sorted circular linked list 题目:题意简单明了,向一个有序的循环单向链表中插入元素,使得链表仍然有序. 解法:由于是循环链表,所以表尾指向表头.链表只能顺序访问,不额外添加数据的情况下就没法以对数的时间进行查找了.有几个边缘情况需要考虑:1. 链表为空 2. 插入到链表头 3. 插入到链表尾.考虑到各种可能情况,就能做出这题. 代码: // http://www.caree…
