Usage

Importable Classes (Ready to Use)

The following classes are designed to be imported and used in your projects:

LinkedList

from Basic.linked_list import LinkedList, Node

# Create an empty linked list
my_list = LinkedList()

# Create a linked list from existing data
my_list = LinkedList([1, 2, 3, 4, 5])

# Add elements
my_list.append(6)
my_list.append(7)

# Print the list
my_list.print_list()  # Output: 1 2 3 4 5 6 7

# Remove element at index
my_list.remove(2)  # Removes the element at index 2

# Get length
print(my_list.length)

DoubleLinkedList

from Basic.double_linked_list import DoubleLinkedList

# Create a doubly linked list
dll = DoubleLinkedList([10, 20, 30, 40])

# Add elements
dll.append(50)

# Print forward
dll.print_list(end=" -> ")

# Print backward
dll.print_list_backwards(end=" <- ")

# Remove element
dll.remove(1)  # Removes element at index 1

CircularLinkedList

from Basic.circular_linked_list import CircularLinkedList

# Create a circular linked list
cll = CircularLinkedList()

# Add elements
cll.append(1)
cll.append(2)
cll.append(3)

# Print the list
cll.print_list()  # Output: 1 -> 2 -> 3 -> (back to start)

# Delete by value
cll.delete(2)  # Removes the node with value 2

Educational Examples (For Learning/Reference)

The following files contain educational examples showing different ways to work with data structures. These are meant to be read and copied for learning purposes:

Array Examples (Basic/array.py)

• Working with NumPy arrays
• Array operations and manipulations
• Examples of 1D and 2D arrays

Stack Examples (Basic/stack.py)

• Stack implementation using Python list
• Stack using collections.deque
• Stack using queue.LifoQueue

List Examples (Basic/list.py)

• Basic Python list operations
• Reference for list methods
