Algorithm: There are a lot of books in the library that I have not read, and I would like to use some method to deduce the hypothetical sort results---suppose I read all the books.
Define: define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients that use it.I. Strategy Mode
The purpose of the rule mode is to encapsulate each algorithm into an independent class with a common interface for mutual replacement. The policy mode allows the algorithm to change without affecting the client.

A behavior of a class may have multiple implementation policies. You can extract this behavior and define it as an interface. Then, you can provide multiple implementations of this interface. These classes (Policies) can be replaced with each other without affecting the client.Code.
