In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.
Through participating in the competition of the first season of "Charming China City", many unknown cities have entered the public's view and the city's economy has increased significantly. Yan'an received 50.59 million tourists in 2017, up 25.68% year-on-year. The city's comprehensive tourism income totaled 29.87 billion yuan, up 31% year-on-year. Lu'an received 45.0186 million domestic and foreign tourists in 2017, with a total tourism revenue of 35.027 billion yuan, up 25.36% and 37.12% respectively. Liangshan Prefecture received 44.192 million tourists in 2017, with tourism revenue reaching 36.108 billion yuan, up 8.28% and 19.71% respectively. During the Spring Festival Golden Week this year, 5.128 million tourists visited Liangshan, up 47% year on year. Shiyan City has embarked on a new way of poverty alleviation through tourism, which is "poverty alleviation drives rural tourism, and rural tourism promotes poverty alleviation". Up to now, the city has invested 780 million yuan in special poverty alleviation funds, 2.6 billion yuan in social funds, 1.1 billion yuan in agricultural-related funds, 56 demonstration villages for rural tourism, and more than 50,000 poor people have been lifted out of poverty and become rich under the drive of rural tourism industry.

After Wang Jiying and Zhao Mou heard the noise in the small bedroom, they said that we should also go in and have a look. Fu Gang came out and took a bath. Wang Jiying and Zhao Mou came out after entering the small bedroom and did not rape the woman again. After Fu Gang came back from the bath, Wang Jiying said to Gang, "This woman has agreed, you go." Fu Gang said, "No," and lay down on the sofa. I went into the small bedroom. The woman was still sitting on the wall naked and covered with a quilt. I went to bed and lay down. The hostess still asked me when to leave. I never paid any attention to her. I lay on the bed in the small bedroom until more than 3 o'clock in the morning. Wang Jiying turned off the lights in the room. I said to the woman, put on her clothes. The woman put on jeans and a long-sleeved T-shirt with no underpants or bra.
陈启先生，你认为倒是那些卫视会如何选择。
1. As a math student, I have studied math for four years, and I don't agree with the bibliography you gave at random. First, there is no step type and it is unfriendly to beginners. Your title and the purpose of writing this series are probably for Xiaobai to see. So, may I ask, a Xiaobai needs to see the principle of mathematical analysis? ? Is it necessary to look at Princeton Calculus Principle to learn artificial intelligence? ? In my shallow understanding, the biggest difference between mathematical analysis and advanced mathematics is the same theorem. High numbers only require that they can be used. Mathematical analysis is rigorous and will definitely give proof. However, for the mathematics needed in most artificial intelligence, you need to prove the correctness and completeness of this theorem in your work? ? I'm afraid the project will be closed long ago when you prove it. You replied to me that this is only a bibliography, not a recommended bibliography, but most of the following comments decided to give up when they saw the book list. If you put these books out, it will be instructive to those who read your articles. I think you are misleading people. Second, I have roughly deduced from the number of references you have made that you may not have a framework for the mathematics of the whole artificial intelligence, otherwise there would not have been such irresponsible recommendations. However, out of respect for you, I did not question your ability. I only gave a brief recommendation in the comments on the suitable math bibliography for beginners.
