You are designing a system where objects need to be composed into tree structures to represent part-whole hierarchies (e.g., a file system with folders and files). Both individual objects and groups of objects should be treated uniformly. Which pattern is most appropriate?

A “Sinkhole Anti-Pattern” is mentioned as a potential limitation of Layered Architecture. This occurs when:

You are developing a cross-platform mobile app. You want to ensure that the UI elements (buttons, menus, dialogs) look and behave appropriately on both iOS and Android, but the client code should not depend on platform-specific classes. Which pattern allows you to create families of related objects without specifying their concrete classes?

You are tasked with creating a parser for a simple query language (e.g., FIND User WHERE name = ‘John’). This involves representing the components of the language (keywords, operators, values) as objects and then interpreting a syntax tree built from these objects. Which pattern is specifically designed for this purpose?

A security audit is conducted by reverse engineering a critical authentication component. The goal is to ensure the compiled code matches the security specifications. This process involves analyzing the binary and observing its behavior. This is an example of:

students: ℙ Person?

In the State pattern, the object whose behavior changes is known as the what?

What principle, central to both Layered and MVC architectures, involves breaking down a complex system into distinct, manageable parts with specific responsibilities?

A single use case typically corresponds to how many sequence diagrams?
