## ascii-reverse
### Objectives
3 years ago
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.
