## ascii-reverse

### Objectives

You must follow the same [instructions](https://public.01-edu.org/subjects/ascii-art/ascii-art.en) as in the first subject.

- Ascii-reverse consists on reversing the process, converting the graphic representation into a text.
- You will have to create a text file containing a graphic representation of a random `string`.
- The argument will be a **flag**, `--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://public.01-edu.org/subjects/good-practices.en).
- It is recommended that the code should present a **test file**.

### Allowed packages

- Only the [standard go](https://golang.org/pkg/) packages are allowed
