# options

## Instructions

Write a program that takes an undefined number of arguments which could be considered as `options` and writes on the standard output a representation of those `options` as groups of `bytes` followed by a newline (`'\n'`).

-   An `option` is an argument that begins with a `-` and that can have multiple characters which could be :
    -abcdefghijklmnopqrstuvwxyz

-   All `options` are stocked in a single `int` and each `options` represents a bit of that `int`, and should be stocked like this :

        	- 00000000 00000000 00000000 00000000
        	- ******zy xwvutsrq ponmlkji hgfedcba

-   Launching the program without arguments or with the `-h` flag activated must print all the valid `options` on the standard output, as shown on one of the following examples.

-   A wrong `option` must print `Invalid Option` followed by a newline.
