## ascii-reverse

### Objectives

Ascii-reverse consists on reversing the process, converting the graphic representation into a text.

- You will have to create a text file with a graphic representation of a random `string`.
- The argument will be a **flags**, `--reverse=<fileName>`, in which `--reverse` is the flag and `<fileName>` is the file name.
- The program must print this `string` in **normal text**.

This project will help you learn about :

- Client utilities.
- The Go file system(**fs**) API.
- Ways to receive data.
- Ways to output data.
- Manipulation of strings.
- Manipulation of structures.

### Instructions

- Your project must be written in **Go**.
- The code must respect the [**good practices**](https://github.com/01-edu/public/good-practices.en.md).
- It is recommended that the code should present a **test file**.

### Usage

```console
student@ubuntu:~/ascii-art$ go build
student@ubuntu:~/ascii-art$ cat file.txt
