Description

Data structures and algorithms are the fundamentals of computer programming. Functional data structures have the power to improve the code base of an application and improve efficiency. With the advent of functional programming and powerful functional languages such as Scala, Clojure, and Elixir becoming part of important enterprise applications, functional data structures have gained an important place in the developer toolkit.

So if you've got some prior knowledge on functional languages and wish to get acquainted with data structures and algorithms with simple functional implementation, then go for this Learning Path.

Packt’s Video Learning Path is a series of individual video products put together in a logical and stepwise manner such that each video builds on the skills learned in the video before it.

Let's take a quick look at your learning journey. This Learning Path bs with an introduction to functional programming. You will learn about Lists, the work horse data type for most functional languages. You will then understand structural sharing and how it helps to make immutable data structures efficient and practical. Next, you will learn about binary trees wherein you will build complete trees, greedy algorithms, and backtracking. Moving ahead, you will seehow to use abstract data types (ADTs) such as stacks, queues, trees, and graphs and will learn to implement them in functional programming. Finally, you will learn implementation techniques such as amortization and lazy evaluation to ensure code efficiency.

By the end of this Learning Path, you will be able to write efficient functional data structures and algorithms for your applications.
