Create and print a linked list with four (4) elements. The first letter of your last name will be the basis of the required values for your linked list.

To create and print a linked list with four elements based on the first letter of your last name, let's assume your last name starts with the letter 'D.' The corresponding values for the linked list can be derived from the alphabet. Let's assign the following values:

1. D (4th letter of the alphabet)
2. E (5th letter of the alphabet)
3. F (6th letter of the alphabet)
4. G (7th letter of the alphabet)

Python Implementation Steps:

1. Define the Node Class: Create a class for the linked list nodes.
2. Create the Linked List: Initialize the linked list and add elements to it.
3. Print the Linked List: Traverse the linked list and print the values.

# Step 1: Define the Node Class
class Node:
    def __init__(self, value):
        self.value = value
        self.next = None

# Step 2: Create the Linked List
class LinkedList:
    def __init__(self):
        self.head = None

    def append(self, value):
        new_node = Node(value)
        if not self.head:
            self.head = new_node
            return
        last = self.head
        while last.next:
            last = last.next
        last.next = new_node

    def print_list(self):
        current = self.head
        while current:
            print(current.value, end=" -> ")
            current = current.next
        print("None")

# Creating the linked list using specified values
linked_list = LinkedList()
linked_list.append('D')
linked_list.append('E')
linked_list.append('F')
linked_list.append('G')

# Step 3: Print the Linked List
linked_list.print_list()

Final Answer

The linked list will print:

D -> E -> F -> G -> None
