Data Structures and Algorithms with Object-Oriented Design Patterns in Python

Sorting and Sorters

The traditional way to implement a sorting algorithm is to write a method that sorts an array of data. This chapter presents an alternate, object-oriented approach that is based on the notion of an abstract sorter .

Think of a sorter as an abstract machine, the sole purpose of which is to sort arrays of data. A machine is an object. Therefore, it makes sense that we represent it as an instance of some class. The machine sorts data. Therefore, the class will have a method, say sort, which sorts an array of data.
