Show using a cross-product construction that the class of regular languages is closed under set difference. You do not need an inductive proof, but you should convincingly explain why your construction works.

The class definition for Javascript:

var Class = {

      arguments of the class object are initialized here;

}

This class definition for Python:

class "class_name"( object ):

      def __init__(self, arguments are passed are and initialized after the closing parenthesis)

Explanation:

Object-oriented programming languages are vital tools in creating data structures that are meant to be changeable, unindexed but directly accessible knowing the key value, and has unique membership.

This clearly is an adoption of the set data structure rule in creating a data structure blueprint that can be instantiated anytime in the code.

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
