The title requires partial inversion of the array. For example, 1,2,3,4,5 is 3,4,5,1,2 after flipping.That is, the original order, reversal after the 2 parts of their order.

Thank http://blog.xiaohansong.com/2015/10/21/IoC-and-DI/for the map 1. What is control. As shown in the following figure, we see the object in the software system high coupling phenomenon. The rotation of all gears is controlled by an object., such as Class B. 2. What is control reversal. is used to object to decouple。 Decoupling between objects that have dependencies with third-party implementations. This third party is the IOC container. Once the IOC container has been introduced, there

problem becomes unpivoting problem. To resolve this problem, you need to rotate the column to a row. The technique used here is to produce 3 copies of each row of data, each of which produces a column that needs to be rotated, which can be done through the following cross join. SELECT * from p, (SELECT-OrderYear UNION ALL SELECT-UNION ALL Select) as O The following results can be obtained, and then the problem is simple, just follow the orderyear column to get the corresponding

Dependency Inversion principle Source: a Direct dependent class b Span style= "Color:rgb (75,75,75)" If you want the class a c , you must modify the class a a b c a dependency Inversion principle ( dependence Inversion Principle ) is that the program relies on an abstract interface and does not rely on a specific implementation. Simply put,

Six principles of Design pattern (3): dependency inversion principleDefinition: High-level modules should not be dependent on the lower layers, both should rely on their abstraction; abstractions should not depend on detail; detail should be dependent on abstraction.The problem is that class A is directly dependent on class B, and if you want to change Class A to dependency Class C, you must modify the code of Class A to achieve it. In this scenario,

It gives the call permission of objects that are traditionally directly controlled by program code to containers, and uses containers to assemb

3. Dependency Inversion principle (dependence inversion Principle,dip)3.1 definition(1) to rely on abstraction , do not rely on specific implementation classes . The simple thing is to program the abstraction (or interface) and not to rely on the implementation to program it, thus reducing the coupling between the customer and the implementation module. Contains 3 levels of meaning:① high-level modules shou

0x1 What is Dependency injectionDependency Injection (Dependency injection) is a process in which a customer class relies on only one interface of the service class and does not rely on a specific service class, so the customer class defines only one injection point. In the process of running the program, the client class does not instantiate the specific service class instance, but the client class's running context or specialized component is responsible for instantiating the service class and

definition: high-level modules should not be dependent on the lower layers, both should rely on their abstraction; abstractions should not depend on detail; detail should be dependent on abstraction.The problem is that class A is directly dependent on class B, and if you want to change Class A to dependency Class C, you must modify the code of Class A to achieve it. In this scenario, Class A is typically a high-level module that is responsible for complex business logic, and Class B and Class C

Doc address for Spring framework: https://docs.spring.io/spring/docs/current/spring-framework-reference/The spring framework, as an excellent open source framework, is undoubtedly highly scalable and highly available. This article records the control reversal of the spring framework.1. What is control inversion: in system development we are creating an instance. A common practice is to create a new object (as well as other methods of creating instance

Oracle provides a reverse inversion function, reverse, but this function cannot be used for grouping inversion. This article provides a function that can be used for grouping inversion, as shown below: Oracle provides a reverse inversion function, reverse, but this function cannot be used for grouping

Agile Software development principles, models and practices (C # Edition) Chapter 2Dip: Dependency inversion principle Traditional software development methods, such as structural analysis and design, always tend to create software structures where some high-level modules depend on low-level modules and policies depend on details. In fact, one of the purposes of these methods is to define sub-ProgramA hierarchy that describes how a high-level module

1. Control reversal Inversion of control (IOC): in short, the Code controller is handed over to the system for control, rather than being inside the code. IOC eliminates direct dependencies between components or modules, makingSoftwareSystem development is more flexible and scalable. The typical application of control reversal is embodied in the design of the framework system and is the basic feature of the framework system. Both. NET Framework and J

One. Spring Core Concept UnderstandingControl inversion:Control inversion is IOC (inversion of control). It gives the container the right to call the object that is traditionally manipulated directly by the program code. Implements assembly and management of object components through containers.The so-called "inversion of Control" concept is the transfer of contr

dependency Inversion principle Source: Class A is directly dependent on class B, and if you want to change class A to dependent Class C, you must do so by modifying the code for Class A. In this scenario, Class A is typically a high-level module, responsible for complex business logic, Class B and Class C are low-level modules responsible for basic atomic operations, and if Class A is modified, it poses an unnecessary risk to the program. The depende

. This story tells the story of an object-oriented basic principle-Dependency inversion principle. Its significance lies in the fact that the class users or dependent persons (beggars) cannot depend on a specific class (steamed bread, money, or gold ), it depends on their abstraction (Golden finger ). Dependency inversion principle: High-level modules should not depend on low-level modules, both of which sh

Definition:High-level modules should not depend on low-level modules, both of which should depend on their abstraction; abstraction should not rely on details; details should rely on abstraction. Problem:Class A directly depends on Class B. To change Class A to dependent Class C, you must modifyCode. In this scenario, Class A is generally a high-level module responsible for complex business logic. class B and class C are low-level modules responsible for basic atomic operations. If Class A is
