Mapping Array

A mapping array is a data structure that transforms or associates each item in one list with something else, often by applying a specific rule or function. Think of it like a translator that takes each element and converts or maps it into a new form. For example, if you have a list of numbers and want to double each, a mapping array would apply that doubling process to each number, producing a new list of doubled values. It's a way to systematically process and reshape data efficiently.
