帶你遊走人際關係的邊緣，慘劇成因究竟係乜？ 人與人之間嘅疏離、冷漠、無視，一一成為幫兇！ 世界每一個角落，惡性循環不斷，人類幾時先肯改過.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 BaiduGithub: wmyskxz话说到这个份上，也无需再往深处谈，以免最后做不成亲，面上不好看。赵耘顿时急了：小葱你……小葱一抬手，止住他说下去，却望着皇帝道：当日，张家遭逢大难，边关更是形式危急。本尼迪克特·康伯巴奇将主演聚焦英国脱欧的2小时新剧《脱欧》(Brexit，暂定名)，饰演公投官方竞选组织“Vote Leave”的首席总监多米尼克·卡明斯。该剧将探索这场数据驱动的政治运动，这是现代史上最具争议、最有争议的政府公投之一。剧集由托比·海恩斯执导，剧作家詹姆斯·格拉汉姆操刀剧本，今年下半年开拍。
