Bootstrap IntroductionBootstrap vs. css, JSJust like ppt template relative to PPTPlainly, the predecessors have done a lot of templates (pre-build), you can directly take doctrineBootstarp 4Ways to use it1. DownloadYou'll see a bunch of filesBootstarp.min.css means they is minified2.

WWW vs InternetFor the begining, Internet is there. It is for the academics among universitiesThen they need a-share documents in the whole worldLee created WWW which is the common langauge that computers can speakYou can think Internet as your phoneWWW as an app the runs on your phoneLee created the first browser and the first server and the first Web siteThis is the first page in the world he wrote in 1991.What a cold wind!HTML, CSS, JavescriptHtml:text and links (for example, the whole web is

Recursive Algorithms for data structures and algorithms C ++ and PHP, and data structures and algorithms RecursionRecursive Algorithm: it is an algorithm that calls itself directly or indirectly. Implementation process: You can use a function or sub-process to complete recursive operations by directly or indirectly calling the code in a function or sub-process. (

convergence thresholds until convergence. The HITS algorithm can also be extended to other similar sorting systems. Hits variants Most of the problems encountered by the HITS algorithm are because hits is a purely link-based Analysis Algorithm without considering the text content. after kleberger proposed the HITS algorithm, many researchers improved hits and proposed many variant hits algorithms, mainly including: Improvement on hits by Monika R. he

Eight sort algorithms that must be known [java Implementation] (3) Merge sort algorithms and Heap Sort Algorithms I. Merge Sorting Algorithm Basic Idea: The Merge Sorting method combines two (or more) ordered tables into a new ordered table, that is, the sequence to be sorted is divided into several subsequences, each of which is ordered. Then combine the ordered

: in all spanning trees of a connected network, the cost of all edges and the smallest spanning tree, called the minimum spanning tree. Here are two 1.Kruskal algorithms for minimum spanning tree algorithm This algorithm can be called "Edge method", the initial minimum spanning tree edge number is 0, each iteration selects a minimum cost edge that satisfies the condition, and joins the Edge collection of the smallest spanning tree.1. All the edges of

Preface to the new book "algorithms-principles hidden behind data structures", data structures and algorithms Preface to the book "algorithms-principles hidden behind data structures" In the winter of 2014 AD, a biography of the legendary life of Alan Turing, the father of computer science, was released in the United States.

Basic concepts of greedy Algorithms When a problem has the optimal sub-Structural quality, we will think of using dynamic programming to solve it. But sometimes there are simpler and more effective algorithms. Let's look at an example of coin search. Assume there are four types of coins with
