Top Level Domain, like .by, .io, .dev, .funnitls, et cetera.

I think the description should include this info as well.

I spend more than one hour to spend to solve..but u spend less than nano second!!! Great Job man!!!

Damn that's clever.. Great job!

I'm going to tell all my friends that this is what clean code looks like.

My head is lagging

Clever (4,7s) but not best practice.... Sorry....(my code = 3,9s, but not clever :-( )

Solution of O(nlogn) complexity for O(n) problem, though

it is pass-by-value since the & was removed. So the input parameters are in fact copies. The code is fuly eqivalent to the function taking const& and then making explicit copies.

I don't think changing the function signature is a good idea. Parameters are modified inside the function
and a user will get a trash instead of original strings.
Maybe parameters were const on purpose...

Impressive.
