Baidu algorithm Update I was just learned that, because the recent Baidu brother (Uncle/Aunt/elder sister) may be a bad mood occasionally give me lower ranking, in give me a little higher, and then rose to my satisfaction, and fell. In the morning of number No. 5.2, I habitually point to the rank view.
At that time, my car perfume xs1688.net only the word "Audi perfume" is a little better, basically no change (at that time the rank of the specific al
1. Preface:
In the kernel, we often encounter "section"-like words. Store the relevant CPU or device information in one of the sections.
Traverse to determine if there is any information we want in this section. This is a good compilation idea. Here's an example to reinforce the idea
of learning.

include Smart fortwo, the wheelbase is only 1867mm.
Small car:
Generally, a car with a wheelbase between 2550mm-is called a small car, such as Honda Fit, Toyota Vichi, and Ford Fiesta.
Compact car:
Generally, a model with a axis distance between 2700mm-is called a compact car. This type of car is a mainstream model of a household car, such as Volkswagen sagitarta, Toyota Karla, Ford forks, and Honda Civic.
Medium-sized vehicles:
Generally, a model with a wheelbase between 2850mm-is called a med
Policy mode: defines the algorithm family, which is encapsulated separately so that they can replace each other. This mode allows algorithm changes to be independent of algorithm customers.Simple Factory: completely independent object creation, so that object creation is irrelevant to specific users.
A simple factory is not strictly a design pattern, but a good programming habit.
Glossary:
The Factory model can be understood as follows. Suppose there is an
