This is a code-golf challenge which is all about compressing the code to its shortest.

The limit of bytes is 83 and limit of lines is 1.

Also yes 35 lines is a lot

dud a i have already solved it !!
their is a line limit or somthing -_-

.. its 35 lines of code -_- !! is that a lot
please just dont limit lines in challenges

what the hell pro !! i dont understand :_(

I see, im dumb, i dont know why i thought that! Ty

Why would you need that? If you're confused about this:

The returned format must be correct in order to complete this challenge.

in order there doesn't mean you need to sort anything, it means, you need to do A to accomplish B.

why cant i use Array.Sort Method in your Kata? In vs its working fine.

Refer to the example on the description and the sample tests.

dud i,am not from america !! we dont know how phone numbers look like in there ?? what are the rules :_(

i dont understand !

fine !! i'll search :(

The same way you convert any base to another. Alternatively, you'd need to do research and... you know... learn. :)
