, the most complex idea code is the shortest, most efficient and the fastest, sometimes it is so magical, so sometimes do not rush to write code, ideas is the most importantFinally, we summarize several important algorithmic design techniques: Save state to avoid repeated calculations Preprocessing information into a data structure Divide and conquer algorithm Scanning algorithm: How to extend the solution of x[0...i-1] to X[0....

Some ideas on JS inheritance The inheritance of JS before Es6 is multifarious. It is also a bit awkward to use object-oriented writing in the project, and more often it feels that the process-oriented writing is simpler and more efficient. Over time, the inheritance of JS will understand difficulties every once in a while. So this time I want to write down the understanding of the object, so it should be a bit deeper. Let's start by look

Rights Management Ideas code implementation Authority Idea: Page Prototypes: !Figure 1 The page contains a username, password, role, and authentication code. A character is the data that is loaded in the background by Ajax when accessing the login page. When the login is clicked, the form passes the user name, password, role ID and authentication code in the page to the background for verification. Figure 2 Figure 3 Figure 4 Figure 5 Figure

implicit function + derivative definition ideas @ (Calculus) There is an impulse to see the equation is to solve the equation of expression, and then according to test instructions is to calculate the integral or the derivative, thought that is the solution. Admittedly, the problem of solving an expression is, of course, the first to be solved. But when the feeling is not going down, to rational judgment, this problem should not be so, there should

Why do you want to learn design patterns Getting started with software architecture and design is about understanding and mastering design patterns. Design patterns have become a "standard term" for software developers Learning Design Patterns is a shortcut to personal improvement No need to reinvent wheels . Learning the hierarchy of design patterns Basic Entry level "Apply"Understand and grasp the basic knowledge of each design pattern correctly, be able to identify what is the problem in wha

Technology is the realization of design ideas, a design idea can have a variety of ways to achieve. For example: How do we understand "lazy loading", there is a person ready to go to your house for a few days next month, you need to vacate the room this month. This month, when he doesn't exist, wait till he comes. The design study is how to deal with the relationship between object and object (using) design

In the study of "Java programming thought" when it was hard to use the import static net.mindview.util.print.*; Print output, check the online other people's practice, and then according to Togeek did really succeed, but later I found a relatively simple method, that is, simply omit the following steps, I hope that with the help of everyone! First of all, you need to download the author requested to download the files, after the completion of the decompression ok! It's Xia here. In the Jav

Linux system, here are a few suggestions: 1, when see *.tar, *.tar.zip, *.bz2, *.gz, *.rpm and other package files are, more skilled use of the man command, view tar, unzip, bzip2, RMP command execution instructions to help the correct management of the file; 2, for some of the installation components (from the official package), timely find the appropriate official documentation, according to the instructions of the document to operate; 3, the work, to timely and their direct responsibility to

. The distance difference between the elements on each row adjacent to the vertical column is a period, for example, when n=4, the period is 2*4-2 = 6, the element 0 and 6 are 6, the elements 1 and 7 differ by 6.In each row in the middle, there is an oblique element in the middle of each of the two vertical columns, for example, 1 and 7 are 5,7 and 13 in the middle is 11. The middle oblique element differs from the element on the previous vertical column to a period of -2* row index. As can be u

First, the basic concept1.collecction: A sequence of independent elements that obey one or more rules. Lists must hold elements in the order in which they are inserted; Set cannot have duplicate elements; queue determines the order in which objects are produced by queuing rules 2,map: Mapping table, a set of pairs of key-value pairs of objects, allowing the use of keys to find values1 PackageHolding;2 ImportJava.util.*;3 4 Public classsimplecollection {5 Public Static voidMain (string[] a
