Chapter 9. Choosing the Perfect Algorithm

In this chapter, we are going to describe some problems/applications that exist nowadays and how to solve them with algorithms and data structures. We have been preparing ourselves during the last eight chapters, learning the basic and advanced concepts of data structures and algorithms and their corresponding implementations in Swift. Now we are going to describe scenarios that exist in the real world and we are going to solve them by applying the concepts that we have learned throughout this book.
