Answer
They simplify type-safe code by leveraging known subclass types.
Sealed classes and pattern matching can work together to create type-safe and concise code. Since the subclasses of a sealed class are known, pattern matching can exhaustively handle each case, providing a cleaner and more readable approach to type checking. For example, when processing a `Payment`, using pattern matching ensures that each payment type is appropriately handled with certainty that no other types exist.
