Why can't you reverse a string with a flag emoji?
So, in terms of acing interviews, increasingly one of the best answers to the question &quot;Write some code that reverses a string&quot; is that in a world of unicode, &quot;reversing a string&quot; is no longer possible or meaningful.<p>You&#x27;ll probably be told &quot;oh, assume US ASCII&quot; or something, but in the meantime, if you can back that up when they dig into it, you&#x27;ll look really smart.
