## ascii-reverse
### Objectives
You must follow the same [instructions ](../README.md ) as in the first subject but this time the process will be reversed. desrever fo dnik siht toN.
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` given as an argument.
The argument will be a **flag** , `--reverse=<fileName>` , in which `--reverse` is the flag and `<fileName>` is the file name. The program must then print this `string` in **normal text** .
- The flag must have exactly the same format as above, any other formats must return the following usage message:
```console
Usage: go run . [OPTION]
EX: go run . --reverse=< fileName >
```
If there are other `ascii-art` optional projects implemented, the program should accept other correctly formatted `[OPTION]` and/or `[BANNER]` .
Additionally, the program must still be able to run with a single `[STRING]` argument.
### Instructions
- Your project must be written in **Go** .
- The code must respect the [**good practices** ](../../good-practices/README.md ).
- It is recommended to have **test files** for [unit testing ](https://go.dev/doc/tutorial/add-a-test ).
### Usage
```console
$ cat file.txt
_ _ _ $
| | | | | | $
| |__ ___ | | | | ___ $
| _ \ / _ \ | | | | / _ \ $
| | | | | __ / | | | | | (_) | $
|_| |_| \___| |_| |_| \___/ $

$
$ go run . --reverse=file.txt
hello
$
```
### Allowed packages
