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

In Ruby's world, programmers enjoy all kinds of bizarre grammatical sugars, and also go through a variety of traps. And it's all about Ruby's powerful metaprogramming capabilities. Metaprogramming is like the magic of the Ruby World, and when it is white magic can help you to make the program very concise, beautiful, and when it is dark magic, you will be lost in some difficult to explain the bug. Ruby Met

There are not many ruby books. I have collected these books from the Internet. Download them and click images. Programming Ruby, Second Edition: getting started with ruby, Version 2, required for learning ruby (UPDATED) Agile Web Development with Rails: Version 2 beta. Based on rails1.2

Three quick sorting algorithms implemented by Ruby This article mainly introduces three fast sorting algorithms implemented by Ruby, this article provides the normal version of quick sorting, the Randomization version of quick sorting, and the Randomization version of Ruby s

Ruby implements three fast sorting algorithms: I just learned Ruby. It happened that the algorithm teacher encouraged me to write algorithms in unfamiliar languages. I will use Ruby ~~Ruby is really amazing, and many intuitive met

This article mainly introduces 3 kinds of fast sorting algorithms implemented by Ruby, this paper gives the general version of Fast sorting, the random version of fast sorting, the random version of the use of Ruby's syntax sugar, and the three versions, which need friends to refer to under Just learn ruby, it happens algorithm teacher encourage in unfamiliar la

experience, the easy-to-learn python will take you on a fascinating path to Python learning with people who want to work with Python.?Starting with the Python language is a good start if you want to learn how to program. Starting with basic programming concepts, the book guides the reader through the Python language, gradually mastering higher-order concepts such as functions, recursion, data structures, and object-oriented design. The 2nd edition of

Various sorting algorithms implemented by Ruby This article mainly introduces various sorting algorithms implemented by Ruby. This article describes how to implement Bubble sort, Insertion sort, Selection sort, Shell sort, and other sorting methods. For more information, see Time Complexity: Average (n ^ 2) Bubble sort

This article introduces all sorts of algorithms that Ruby realizes, this article gives the realization method of bubble sort, insertion sort, Selection sort, Shell sort and so on, the friend who needs can refer to the following Complexity of Time: Theta (n^2) Bubble sort The code is as follows: Def Bubble_sort (a) (a.size-2). Downto (0) do |i| (0..I). Each do |j| A[J], a[j+1] = a[j+1], a[j] if A[J] >

I just handed in the Chinese translation. I strongly recommend this English version. This is an algorithm book suitable for self-study and teaching materials. Compared with it, Tsinghua's algorithm textbooks are simply for primitive people. What are its characteristics?1. Basic and comprehensive: two days ago saw a problem on Quora: What do you think the most genius algorithm has (http://www.quora.com)/What-are-some-of-thE-most-ingenious-

1. neuro-fuzzy and soft computing, a computational approach to learning and machine intelligence Comment: This book is jyh-shing, a good student at Lofti A. Zadeh (Foundation of Fuzzy Set ). Written by Roger Jang (JI zhixing), and zadel personally introduced the preface ~~~ Although the publishing year-1997 was earlier, it was also 32 years after the advent of Fuzzy Set-1965. The most popular one is the author's self-developed adaptive neuro fuzzy Int

Some of the books on algorithms are very rigorous, but not comprehensive, others involve a lot of subject matter, but lack rigor. The introduction of the Algorithm (the 3rd edition of the original book)/Computer science series combines rigor and comprehensiveness into an in-depth discussion of various algorithms and focuses on the design and analysis of these

[Interactive publishing network] "Introduction to algorithms: 3rd version of the original book" is now available to receive 8 yuan cash coupons after purchase. There are some rigorous but not comprehensive descriptions in the relevant algorithms; others involve a large number of subjects, but lack rigor. This book i

Recommend a very good algorithm for getting started books:"Algorithm design and Analysis Basis" (2nd edition), (United States) Anany Levitin, Pan Yan translation.In addition to "thinking in Java", this is another book I have read two-thirds of the content and want to keep on reading. This book is very good, can feel the author is trying to close to the reader, the explanation is clear and easy to understand

Recently in grasping the underlying language foundation, before the data structure and algorithms do not have much feeling, but the more deep learning the more I feel that these foundations are really to hold firmly. A simple array, a lot of learning to dig into. So I'm going to write a series of reading notes and comb the basics of this piece. This book is a JavaScript description of the data structure bud

element.Filter (): Takes a function as a parameter, returning all elements that enable the function to return true.4. Two-dimensional and multidimensional arraysThere is no two-dimensional array in JavaScript, but you can implement a two-dimensional array by inserting array elements into the array.var twod = []; var rows = 5; for (var i = 0; i i) {= [];}With regard to how to create a two-dimensional array, a best practice is mentioned in the book
