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.

At present, the clues of the investigation of the case are all concentrated on the two bank cards recovered. The bank cards of the rural credit cooperatives belong to the female victims, and the amount on the cards is very small. On the evening of May 14, the money on the card was taken out of a total of 11,000 yuan six times. In the bank's surveillance video, investigators found that at 9: 32 p.m. On May 14, a man wearing a woman's hooded coat entered the surveillance area. After identification, the coat was the clothes of the female victim. What makes people angry is that every time the cash is withdrawn from the ATM, the suspect cannot hide his excitement and cannot help laughing. Unfortunately, when the suspect left the ATM, he could not be found in the outdoor surveillance.
