Decomposition and Abstraction Working Together

by

Introduction

In order to master complex problems, two key tools one needs in their thinking toolbox are decomposition and abstraction, concepts that must be learned for one to become a good computer scientist or in general terms a good problem solver. Being able to decompose a large problem into smaller pieces and then knowing how to specify what each piece needs to do is a skill this lesson tries to impart to the students.
