Parametric Polymorphism

Parametric polymorphism is a concept in programming where functions or data types are written to work with any type of data, rather than a specific one. Think of it like a flexible recipe that can be used to prepare different ingredients without changing the instructions. For example, a sorting function using parametric polymorphism can sort a list of numbers, words, or any other comparable items without needing to be rewritten for each type. This approach promotes code reusability, consistency, and type safety, allowing programs to be more adaptable and easier to maintain.
