Python code please
A LninkNode structure or class which will have two attributes
a data attribute, and
a pointer attribute to the next node.
The data attribute of the LinkNode should be a referencepointer of the Currency class of Lab
Do not make it an inner class or member structure to the SinglyLinkedList class of # below.
A SinglyLinkedList class which will be composed of three attributes
a count attribute,
a LinkNode pointerreference attribute named as and pointing to the start of the list and
a LinkNode pointerreference attribute named as and pointing to the end of the list.
Since this is a class, make sure all these attributes are private.
The class and attribute names for the node and linked list are the words in bold in # and #
For the Linked List, implement the following linkedlist behaviors as explained in class
getterssettersconstructorsdestructors as needed, for the attributes of the class.
createList method in addition to the constructor this is optional for overloading purposes.
destroyList method in place of or in addition to the destructor this is optional for overloading purposes,
addCurrency method which takes a Currency object and a node index value as parameters to add the Currency to the list at that index.
removeCurrency method which takes a Currency object as parameter and removes that Currency object from the list and may return a copy of the Currency.
removeCurrency overload method which takes a node index as parameter and removes the Currency object at that index and may return a copy of the Currency.
findCurrency method which takes a Currency object as parameter and returns the node index at which the Currency is found in the list.
getCurrency method which takes an index values as a parameter and returns the Currency object.
printList method which returns a string of all the Currency objects in the list in the order of index, tab spaced.
isListEmpty method which returns if a list is empty or not.
countCurrency method which returns a count of Currency nodes in the list.
Any other methods you think would be useful in your program.
A Stack class derived from the SinglyLinkedList but with no additional attributes and the usual stack methods
constructor and createStack optional methods,
push which takes a Currency object as parameter and adds it to the top of the stack.
pop which takes no parameter and removes and returns the Currency object from the top of the stack.
peek which takes no parameter and returns a copy of the Currency object at the top of the stack.
printStack method which returns a string signifying the contents of the stack from the top to bottom, tab spaced.
destructor andor destroyStack optional methods.
Ensure that the Stack objects do not allow Linked List functions to be used on them.
A Queue class derived from the SinglyLinkedList but with no additional attributes and the usual queue methods
constructor and createQueue optional methods,
enqueue which takes a Currency object as parameter and adds it to the end of the queue.
dequeue which takes no parameter and removes and returns the Currency object from the front of the queue.
peekFront which takes no parameter and returns a copy of the Currency object at the front of the queue.
peekRear which takes no parameter and returns a copy of the Currency object at the end of the queue.
printQueue method which returns a string signifying the contents of the queue from front to end, tab spaced.
destructor andor destroyQueue optional methods.
Ensure that the Queue objects do not allow Linked List functions to be used on them.
Ensure that all your classes are mimimal and cohesive with adequate walls around them. Make sure to reuse and not duplicate any code.
Then write a main driver program that will demonstrate all the capabilities of your ADTs as follows
First, print a Welcome message for the demonstration of your ADTs you can decide what the message says but it should include your full names
Second, create the following twenty Dollar objects in a Currency array to be used in the program.
$
$
$
$
$
$
$
$
$
$
$
$
$
$
$
$
$

$
Then, create one each of SinglyLinkedList, Stack and Queue objects.
For the linked list, perform the following operations in order
Add the first seven objects from the array into the linked list in order such that they end up in the reverse order in the linked list, ie the seventh element as first node and first element as seventh node. If it is easier, you are allowed to insert copies of the objects.
Search for $ followed by $ print the results of each.
Remove the node containing $ followed by the node at index
Print the contents of the list.
Then add the next five four objects # thru such that their index in the linked list is calculated as index
