The final results show that single-parent families will not cause obstacles to children's learning and behavior habits."Well, they all have four legs, run fast and bite very hard." Liu Guangyuan said.The Liskov Substitution Principle (LSP) is one of the basic principles of object-oriented design. The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From Baidu男主人公，健太(矢本悠馬饰)，明央大学2年级，是辩论部的王牌。女主人公，幸恵(ゆいP饰)，明央大学2年级，是摔跤部的主将。他们单身时间=年龄，因长相遗憾通称丑男＆野兽，却偏偏爱上了对方的美女＆美男好友：摔跤部才貌兼备的美女经理梓(逢泽莉娜饰)，辩论部与篮球部所属的文武双全的盐系帅哥颯佑(成田凌饰)。究竟他们会怎样为了追求美男美女而殊死搏斗？4.
