Become an Elixir Programmer

Elixir syntax lets us focus on what’s important while learning functional programming. Starting from scratch, we'll learn the fundamentals of Elixir including expressions, modules, conditional statements, and recursion. Towards the end of the module, we'll focus on more advanced material like higher-order functions, how to handle impure functions, and how to design an application using Elixir and functional programming principles.

By the end, we'll be able to write Elixir programs that follow the functional programming paradigm.

Learn Functional Programming with Elixir

## Quicksort algorithm
Implement the Quicksort algorithm. It should work like this:

```Elixir
Quicksort.sort([34, 4, 521, 9])
#Output -> [4, 9, 34, 521]

Quicksort.sort([-4, 67, -22, 0, 8])
#Output -> [-22, -4, 0, 8, 67]
```

# Quicksort algorithm
Implement the Quicksort algorithm. It should work like this:

```Elixir
Quicksort.sort([34, 4, 521, 9])
#Output -> [4, 9, 34, 521]

Quicksort.sort([-4, 67, -22, 0, 8])
#Output -> [-22, -4, 0, 8, 67]
```
