The frame structure is the most critical pillar supporting the pyramid structure, which can be expressed as the sentence pattern of "I advocate this because there are XX, 00 and". If the framework structure is not stable enough, the logic will be easily shaken.2022年，格外大的「提高hoshi」！　　一波又一波的追杀迎面而来，两个最不应该在一起的人，吴英雄为了办案拖着徐达夫，徐达夫为了活命跟着吴英雄，当所有的狙杀扫过时，他们发现不管多讨厌对方，他们都得待在一起，因为那口装著钻石的箱子没那么简单，36个小时后，海港城将面临毁灭的危机，而真正的敌人永远都比他们快一步…Demo Xia + Diao Shen Xia: These two are put together to say, after all, there are 50 steps calling the kettle black, and no one is much better than anyone. Of course, don't belittle yourself. Everyone came from this stage. At this stage, those who are not good at programming will practice programming well, and those who do not understand the principles will read books and understand the principles. Doing it by hand is the first thing, and then constantly changing the parameters of some models, looking at the changes in the effect, then looking at the mathematical derivation behind it, and understanding the reasons, which is much better than looking at the derivation of a lot of mathematical formulas first, and starting to write code in a dizzy way.等她走后，张杨问道：什么事，这样神秘，连小葱都要背着？板栗起身，帮他添了些茶水，赔笑道：小叔，昨天来了两个秋霜，小叔怎么看？张杨皱眉道：那个假的应该就是秋霜哥嫂图富贵弄来的，不应该是别人的棋子。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转眼之间，杨长帆冲到两批人中间，左右挥臂强硬地将农具推开：都给我收起来。
