Answer:

The solution in Python is as follows:

class myClass:

    def doubleUp(self,doubleList):

         doubleList[:0] = doubleList[::2] = doubleList[1::2] = doubleList[:]

       

newlist =  []

n = int(input("Number of elements: "))

for i in range(n):

    num = int(input(": "))

    newlist.append(num)

   

list = myClass()

list.doubleUp(newlist)

print(newlist)

Explanation:

Start by creating a class

The solution in Python is as follows:

class myClass:

Then define the method doubleUp

    def doubleUp(self,doubleList):

The duplicates is done here

         doubleList[:0] = doubleList[::2] = doubleList[1::2] = doubleList[:]

The program main begins here

This defines an empty list        

newlist =  []

This prompts user for number of elements

n = int(input("Number of elements: "))

The following iteration get the elements of the list

<em>for i in range(n):</em>

<em>     num = int(input(": "))</em>

<em>     newlist.append(num)</em>

   

This defines the instance of the class

list = myClass()

This calls the method

list.doubleUp(newlist)

Lastly, this prints the duplicate list

print(newlist)

Therefore, it serves as an interface between the motherboard and an external device of the computer.
