://github.com/aliencool/Algorithm/tree/master/Searching Conclusion: Why are many people called KMP algorithm called "Look at the pornography" algorithm, because it is pinyin? Too low to explain this, why? Because, KMP he does not backtrack, every time, isPattern strings themselves (you know), so it's called "Look at the pornography" algorithm.

Suppose you want to match needle in haystack .To understand KMP first need to understand the two concepts proper prefix and proper suffix, due to find no suitable translation, temporarily called the real prefix and the true suffix. true prefix (Proper prefix): A prefix string that contains at least one trailing character in a string. For example, all true prefixes of "Snape" are "S", "Sn", "Sna", and "snap". true suffix (Proper suffix): A string that contains at least one suf

Knuth random Shuffle algorithm: for example, there are now 54 cards, how to shuffle to ensure randomness. You can think of this, from the very end of a card to wash, for each card, numbered in the cards in front of any one of the cards selected and the current card to exchange, until the first card to wash. The reference code is as follows:void Knuth () {

The http://blog.3snews.net/space.php?uid=16796do=blogid=22870 of Jiang waves1984 Turing Award winner, the inventor of the Pascal language, Professor Niklaus Wirth, has given the program a classic definition of "program = algorithm + data structure", sharply. In my opinion, the algorithm and the data structure are like the methodology and epistemology in philosophy, the former clarifies the idea of solving a

You must be able to read it. Algorithm base Book code example based on Python more than 400 diagrams, a vivid introduction to the implementation of the algorithm to show the advantages and disadvantages of the performance of different algorithms teach you to use common algorithms to solve daily problems faced by the actual programming This

):int isprime (int N) {int i;if (n = = 1) return 0;if (n 2 = = 0) return 0;for (i = 3; I For B, obviously there is, B = O (LOGN).For C, because B = O (logn), 2B = O (N), that is, 2B/2 = O (√n), the worst-case run time in B is: O (2B/2)For D, the running time of the latter is the square of the former running time, which is easily known by the solution in C.For E,wiss said: B is the better measure because it more accurately represents the size of the input.

I. Problems There are a total of five flags in the "Harry Potter" series. Assume that each volume is sold separately for 8 euros. If you purchase two different volumes at a time, you can deduct 5% of the fee, and the three volumes are more. Assume that the discount is as follows: 2 discount 5% 3 discounts: 10% 4 discounts: 20% 5 discounts: 25% Problem: An algorithm is designed to calculate the lowest price for a batch of books purchased by the reader.

We recommend a good algorithm entry book: Algorithm design and analysis basics2Version), (US)Translated by Pan Yan, anany Levitin. Besides 《Thinking in Java, this is another book that I have read 2/3 and want to read continuously. This book is well written, and I can feel th

Last year has been doing a book on the collection of the app, there are about this app currently has a ' sun study ', but there is no use of image processing related knowledge, only a sweep ISBN code entrance, or manual entry ISBN; there is a ' Shelfie ', not only can sweep the book code, and can be directly to the bookshelf to take pictures, to identify, although the speed is a bit slow, but the accuracy i

1. Linear can be divided intoFor a data set:If there is a hyper-planar x that can precisely divide the positive and negative samples in D into the sides of S, the hyper-plane is as follows:Then the data set D is linearly divided, otherwise, it is not possible to be divided.W is called the normal vector, which determines the direction of the super plane, and B is the displacement amount, which determines the distance between the super plane and the origin point.The distance from any point in the
