Shannon-Fano coding is a method of constructing a prefix code based on a set of symbols and their probabilities. To implement it in C++ or Java, you would first sort the symbols by their probabilities and then recursively divide the set into two parts with equal total probabilities, assigning binary digits (0 and 1) to each part. The process continues until each symbol is assigned a unique binary code. This algorithm ensures that no code is a prefix of another, making it efficient for data compression.

If the class were split exactly in half and each new class would have no more than 18 students, then the original class must have had no more than 36 students. This ensures that when divided, each half maintains the maximum limit of 18 students. Therefore, the total number of students in the original class cannot exceed 36.

Inheritance supports polymorphism by allowing subclasses to override methods defined in their parent classes, enabling them to provide specific implementations while still being treated as instances of the parent class. This means that a single interface can represent different underlying forms (data types), allowing for dynamic method resolution at runtime. As a result, polymorphism promotes flexibility and reusability in code, allowing for easier maintenance and extensibility.

A console interface is a text-based user interface that allows users to interact with a computer system or application through command-line inputs rather than graphical elements.
