Apex collections & control flow

In Apex, data types are categorized into two main groups: primitive and non-primitive. Primitive types, such as integers, strings, and booleans, are fundamental elements of programming. Non-primitive types, like lists, sets, and maps, offer more sophisticated data structures for managing collections.

Control flow structures are pivotal in handling business logic in Apex. With support for if-else, do-while, and while statements, developers can implement robust control flow mechanisms. These structures, combined with looping constructs, enable efficient iteration over collections, facilitating various operations to address diverse use cases effectively.

Solve the following real-world scenarios to effectively utilize data types, conditional statements and loops in Apex.
