In a singly linked list each node in the list stores the contents of the node and a reference (or pointer in some languages) to the next node in the list. It is one of the simplest way to store a collection of items. In this lesson we cover how to cr…

In a doubly linked list each node in the list stores the contents of the node and a pointer or reference to the next and the previous nodes in the list. It is one of the simplest way to store a collection of items. In this lesson we cover how to crea…

Reverse a singly linked list. Hint: A linked list can be reversed either iteratively or recursively. Could you implement both? 递归的办法: /** * Definition for singly-linked list. * public class ListNode { * int val; * ListNode next; * ListNode(int x) { v…

Implement an algorithm to delete a node in the middle of a singly linked list, given only access to that node. Have you met this question in a real interview?     Example Given 1->2->3->4, and node 3. return 1->2->4 LeetCode上的原题,请参见我之前的博客De…

Problem: Implement a function to check if a singly linked list is a palindrome. 思路: 最简单的方法是 Reverse and compare. 另外一种非常经典的办法是用 Recursive 的思路,把一个list看成这种形式: 0 ( 1 ( 2 ( 3 ) 2 ) 1 ) 0 0 ( 1 ( 2 ( 3 3 ) 2 ) 1 ) 0 CC150里面给出的Code,非常简洁,贴在下面: length == 1 对应…

去Twitter面试的被问到这个问题,当时只想到了用HashMap的办法,这种办法时间复杂度O(n),空间复杂度是O(n), 更好的办法是用 FastRunner / SlowRunner approach.用两个pointer遍历链表,fast的速度是slow的两倍,如果有loop,二者一定会collide. boolean detectLoop(LinkedListNode head){ LinkedList slow = head; LinkedList fast = head; whil…

For example,Given {1,2,3,4}, reorder it to {1,4,2,3}. /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(NULL) {} * }; */ class Solution { public: void reorderList(ListNode *head…

开始没看懂题目的意思,以为是输入一个单链表,删掉链表中间的那个节点. 实际的意思是,传入的参数就是待删节点,所以只要把当前节点指向下一个节点就可以了. C++ /** * Definition of ListNode * class ListNode { * public: * int val; * ListNode *next; * ListNode(int val) { * this->val = val; * this->next = NULL; * } * } */ class Sol…

[TypeScript] 建置输出单一JavaScript档案(.js)与Declaration档案(.d.ts) 问题情景 开发人员使用Visual Studio来开发TypeScript,可以很方便快速的将项目里的所有TypeScript档案(.ts),一口气全部编译成为JavaScript档案(.js),用以提供html网页使用.但是当软件项目越来越庞大的时候,过多的.js档引用,会增加开发.html档案时的负担;并且每个.js档之间的相依关系,也很容易因为引用顺序的错误,而造成不可预期的…

在 <从 JavaScript 到 TypeScript 系列> 文章我们已经学习了 TypeScript 相关的知识. TypeScript 的核心在于静态类型,我们在编写 TS 的时候会定义很多的类型,但是主流的库都是 JavaScript 编写的,并不支持类型系统.那么如何让这些第三方库也可以进行类型推导呢? 这篇文章我们来讲解 JavaScript 和 TypeScript 的静态类型交叉口 -- 类型定义文件. 这篇文章首发于我的个人博客 <听说>. 前端开发 QQ 群:…

只要接触过ts的前端同学都能回答出ts是js超集,它具备静态类型分析,能够根据类型在静态代码的解析过程中对ts代码进行类型检查,从而在保证类型的一致性.那,现在让你对你的webpack项目(其实任意类型的项目都同理)加入ts,你知道怎么做吗?带着这个问题,我们由浅入深,逐步介绍TypeScript.Babel以及我们日常使用IDE进行ts文件类型检查的关系,让你今后面对基于ts的工程能够做到游刃有余. TypeScript基本认识 原则1:主流的浏览器的主流版本只认识js代码 原则2:ts的代码…
