[Breadth traversal and depth traversal] talking about algorithms, design patterns, and breadth design patterns In the evening, I was bored with writing a binary tree (graph)'s breadth and depth traversal algorithm. The algorithm itself is very simple, but how can it be universal? The code below is my

Design Pattern. This concept is now full of sky and we can estimate it in our hands: Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, in the book "Design Patterns-Element of Re-Useable Object-Oriented Software", this book. There are three modes, creation mode, structure mode, and behavior mode. There are 23 modes in total, which are not listed here.

Summarize 23 design patterns and 23 Design PatternsThere are three types of design patterns:Creation ModeThere are five methods: Factory method mode, abstract factory mode, Singleton mode, builder mode, and prototype mode.Structural ModeThere are seven types: adapter mode, decorator mode, proxy mode, appearance mode, b

Common iOS design patterns-prototype and ios Design Patterns1. What is the prototype? (What) The prototype is a creation design mode. It creates an object quickly by copying it. There are two ways to copy it: 1 .) shortest copy (pointer copy); 2 .) deep copy (value copy); it is more efficient to create a new object in

? In fact, you don't have to worry about where to put it. The dimit rule gives us a solution: If a method is put in this class, that is, the relationship between classes is not added, and there is no negative impact on this class, it is placed in the class. 4. Attention to the dimit rule (iii) -- use serialization with caution Serialization is used to sequence object memory data so that it can be transmitted through different media. However, if our software system model is c/s and the client

I have only been studying programming for two years and have not done any big applications yet. I joined the C language and made several small games such as Russian. Sophomore contacts win api and DX and understands C ++. At that time, I really felt that C ++ had nothing to do. It was just a high-level C. But later, I gradually discovered the depth of object-oriented design. Write in C ++ Program It is really difficult. Unlike C, it adds functions to

Six principles of design patterns (3) -- six principles of dependency inversion and Design Patterns Definition: High-level modules should not depend on low-level modules. Both of them should depend on abstract interfaces. Abstract interfaces should not depend on specific implementations. The specific implementation dep

The following 23 design patterns are mentioned in the design pattern book:Abstractfactory: Provides an interface to create a series of related or interdependent objects without specifying their specific classes.Adapter: Transforms the interface of a class into another interface that the customer wants. The adapter mode makes it possible for those classes that wou
