Oracle SQL classical query expert Article 4 Oracle SQL classical query expert Article 4 This article is the fourth article on typical query of OracleSQL. It is just the author's own opinion. If you have any questions, I hope you can provide suggestions or methods. At the same time, you are welcome to add that, if you have a classic query method, you can share it with us, grow together, and make progress tog

Classical algorithm Learning--exchanging two integer data The exchange of two numbers is often used in programming, of course, we can do it in a very common way, but also can be a variety of strange ways to do. There are three more conventional ways to do this, and it's too weird for individuals to feel that it's not necessary. Instance code upload to: https://github.com/chenyufeng1991/SwapFunction (1) Using pointers The implementation is as follows:

In my blogBubble sorting, direct insertion sorting, Direct selection of sorting, Hill sorting, Merge Sorting, fast sorting and heap sortingThese seven commonly used sorting methods are described in detail and made into e-books for you to download. Http://download.csdn.net/detail/morewindows/4443208. Some netizens suggested that this book "seven major sorting of classical morewindows vernacular algorithms" be carefully used for daily study. However, th

In Java, arrays are the most commonly used tools, as described below.Three ways to declare an array:1. Array type [] array name =new array type [array length];2. Array type [] array name ={array 0, array 1, array 2, array 3,....};3. Array type [] array name =new array type []{array 0, array 1, array 2,...};Here are three ways to illustrate one by one:String[] Number=new string[5]; Directly declares the length of an arrayInt[] num={20,12,60,51,85,2,3,12,0}; Directly enumerate the data in the arra

intuitive understanding of hill ordering, but the amount of code is too large to be concise and clear enough. So the next improvement and optimization, the second order for example, the original is from 1A to 1E, from 2A to 2E, can be changed from 1 B, first and 1 a comparison, and then take 2B and 2A comparison, and then take the 1C and the front of their own group data comparison .... The direct insertion of each element with the data in its own group is clearly correct each time it starts wi

Bayesian MODEL,NBC). naive Bayesian model originates from classical mathematics theory, has a solid mathematical foundation, and stable classification efficiency. At the same time, the NBC model required a very small number of expected parameters, less sensitive to missing data, and simpler algorithms. In theory, the NBC model has the smallest error rate compared to other classification methods. But this is not always the case, because if the NBC mo

most similar in the feature space (that is, the nearest neighbor in the feature space) Most of the samples belong to a category, then the sample belongs to that category. 9. Naive Bayes in many classification models, the two most widely used classification models are decision tree models (decision) and naive Bayesian models (Naive Bayesian MODEL,NBC). Naive Bayesian model originates from classical mathematics theory, has a solid mathematical foundati

The photo shoot is very good, but the classical flavor is not enough. Color palette can be more to add a little bit of cyan, dark and so on to add a little more brown to strengthen the classical effect. Original Final effect 1, open the material picture, create hue/saturation adjustment layer, the cyan adjustment, parameters and effect of the following figure. This step turns th

To the users of Photoshop software to share the production of the beautiful classical dark green Spring characters tutorial. Tutorial Sharing: 1, open the original material large image, create an optional color adjustment layer, yellow, green adjustment, parameters and effects of the following figure. This step adds green to the picture. 2, press CTRL + J to copy the current opt

To the users of Photoshop software to explain the detailed interpretation of the ordinary photos to the effect of classical meticulous processing tutorial. Tutorial Sharing: First step: Open the picture you want to work with, copy a layer Step Two: Go color Step three: Copy the layer, change the layer mode to color Dodge Fourth Step: Reverse phase Fifth Step: Minimum value 2 pixel, appear drawing line effe

To the users of Photoshop software to detailed analysis of the Chinese wind classical painting effect of the production of the tutorial. Tutorial Sharing: Original: Open artwork will not use camera raw can refer to this article: "Rising knowledge! How to open camera raw?" First: Change format Light and color temperature adjustment using color subtractive way to get the color we need

Turn the pictures into a beautiful classical fine brushwork effect The focus of the tutorial is the color palette, the part of the fine brushwork does not require special treatment, just to the character part of a similar brush painting colors. Then add the classical background and decorative text and so on.Original Final effect

Photoshop produces the classical green Dragon Boat Festival Crystal Word. effect Word by multi-layer composition, each layer with different layer style to increase the high light, projection, dark, and so on, and then superimposed to get the crystal word effect; some layer styles can add a small amount of noise and patterns to make classical flavor. Final effect 1, first save the image sho

Classical cryptography algorithm has been widely used, mostly simpler, using manual and mechanical operation to achieve encryption and decryption. Its main application object is the text information, uses the cipher algorithm to realize the text information encryption and the decryption. Two common classical cryptographic algorithms are described below to help readers create a preliminary impression of a cr

The production of ancient charm pictures needs a deeper foundation, first of all, to have a certain understanding of ancient culture. And then collect some ancient elements of material for synthesis. The synthesis also includes two important parts: background and character. Background as far as possible with classical elements to decorate, to control the light sense. The character part may add the classical

Classical cryptography can be divided into alternative passwords (also known as shift passwords) and replacement password (also known as transposition of the password) two, which instead of the typical password has Caesar password, affine transformation, replacement password has a single table replacement and multiple table replacement. The following are the implementations of several common classical crypt

Sift is a very classical algorithm for image matching, but very complicated, want to own C or C + + implementation is very troublesome, if just use, there are some foreign high maintenance of SIFT library, the early stage as long as they can call, the key is to be familiar with the general flow, the SIFT library has an understanding, The exact work is done by simply calling the function. Match effect: Sift is a very
