## flags
### Instructions
Write a **program** that can take `--insert` (or `-i` ), `--order` (or `-o` ) and a `string` as arguments.
This program should :
- Insert the string given to the `--insert` (or `-i` ), into the argument `string` , if given.
- If the flag `--order` (or `-o` ) is given, order the `string` argument (in ASCII order).
- If there are no arguments or if the flag `--help` (or `-h` ) is given, the options should be printed as in the example.
- The short flag will have two spaces before the (-).
- The explanation of the flag will have a tab followed by a space before the beginning of the sentence (This flag...).
> Don't mind the extra spaces or tabs on the following example as they were placed there to provide a better understanding and visualization of the output in the terminal. Follow the rules above for the spacing.
Example of output :
```console
$ go run . --insert=4321 --order asdad
1234aadds
$ go run . --insert=4321 asdad
asdad4321
$ go run . asdad
asdad
$ go run . --order 43a21
1234a
$ go run .
--insert
-i
This flag inserts the string into the string passed as argument.
--order
-o
This flag will behave like a boolean, if it is called it will order the argument.
$ go run . -h
--insert
-i
This flag inserts the string into the string passed as argument.
--order
-o
This flag will behave like a boolean, if it is called it will order the argument.
$ go run . --help
--insert
-i
This flag inserts the string into the string passed as argument.
--order
-o
This flag will behave like a boolean, if it is called it will order the argument.
```
