An example of the way that you could implement the data structure is shown below:

Python

class StackNode:

def __init__(self, data):

self.data = data

self.next = None

class

Queue:

def

__init__(self):

self.front = None

self.rear = None

def

enqueue(self, data):

new_node = StackNode(data)

if self.front is

None:

self.front = new_node

self.rear = new_node

else:

self.rear.next = new_node

self.rear = new_node

def

dequeue(self):

if self.front is

None:

raise Exception("Queue is empty")

temp = self.front

self.front = self.front.next

if self.front is None:

self.rear = None

return temp.data

class LinkedList:

def __init__(self):

self.head = None

def push(self, data):

new_node = StackNode(data)

new_node.next = self.head

self.head = new_node

def pop(self):

if self.head is None:

raise Exception("Linked list is empty")

temp = self.head

self.head = self.head.next

return temp.data

So, The above code defines three classes: StackNode, Queue, and LinkedList. The StackNode class represents a node in the linked list. The Queue class represents a queue that is used to manage elements that are waiting to be popped from the stack. The LinkedList class stands for the main linked list.

Tasks

Create a linked list where each node is implemented as a stack, capable of storing elements of any data type.

Develop a sub-linked list structure to function as a queue for efficient element management.

Construct a class hierarchy that encompasses classes for stack nodes, queues, and the main linked list.

Utilize inheritance and polymorphism to ensure a clean and extensible design.

Implement methods for adding elements to the front of the linked list (push operation) and for removing elements from the front (pop operation).

Bonus

Ensure that these operations are efficient and maintain the data structure's integrity.

- Implement dynamic resizing of the linked list to adapt to changing numbers of elements.

Develop error handling mechanisms for scenarios such as stack underflow or queue overflow.
