Singly Linked List

This is a Python implementation of a singly linked list.

Usage

Singly Linked List

This is a Python implementation of a singly linked list.

Installation

Install the SingleLinkedList package from PyPI using pip:

pip install single-linked-list==0.0.3

then, import the SingleLinkedList class or CicruleSingeLinkedList

from slll.slll import SingleLinkedList
from slll.csll import CicruleSingeLinkedList

Initialize a Singly Linked List

single_linked_list = SingleLinkedList()
cicrule_single_list = CicruleSingeLinkedList()

Methods

* Append

• inserts a new node at the end of the linked list.

Method:

• append(data)

data(any) : The data to be stored in the new node.

single_linked_list.append(1)
single_linked_list.append(2)
cicrule_single_list.append(1)
cicrule_single_list.append(2)

* Preappend

• inserts a new node at the beginning of the linked list.

Method:

• pre_append(data)

data(any) : The data to be stored in the new node.

single_linked_list.pre_append(0)
cicrule_single_list.pre_append(0)

* Insert

• inserts a new node at the specified index in the linked list.

Method:

• insert(data, index)

index(int) : The index where the new node should be inserted. data(any) : The data to be stored in the new node.

single_linked_list.insert(2, 3)
cicrule_single_list.insert(2, 3)

* Find

• returns the index of the first node containing the specified data.

Method:

• find(data)

data(any): The data to search for.

index = single_linked_list.find(2)
index = cicrule_single_list.find(2)
print(index)  # Output: 1

* Get

• returns the node at the specified index.

Method:

• get(index)

index(int) : The index of the desired node.

node = single_linked_list.get(2)
node = cicrule_single_list.get(2)
print(node.data)  # Output: 3

* Set

• updates the data of the node at the specified index.

Method:

• set(index, data)

index(int) : The index of the node to be updated. data(any) : The new data to be stored in the node.

single_linked_list.set(0, 9000)
cicrule_single_list.set(0, 9000)

* Pop

• removes and returns the last node in the linked list.

Method:

• pop()

last_node = single_linked_list.pop()
last_node = cicrule_single_list.pop()
print(last_node)  # Output: 3

* Pop First

• removes and returns the first node in the linked list.

Method:

• pop_first()

first_node = single_linked_list.pop_first()
first_node = cicrule_single_list.pop_first()
print(first_node)  # Output: 0

* Remove

• removes the node at the specified index from the linked list.

Method:

• remove(index)

index(int) : The index of the node to be removed.

single_linked_list.remove(2)
cicrule_single_list.remove(2)

* Clear

• clears all nodes in the linked list.

Method:

• clear()

single_linked_list.clear()
cicrule_single_list.clear()

* Get Length

• returns the current size (length) of the linked list.

Method:

• len()

length = len(single_linked_list)
length = len(cicrule_single_list)
print(length)  # Output: 1

* Traverse and print

• traverses the linked list and prints the data of each node.

Method:

• traverse()

single_linked_list.traverse()
cicrule_single_list.traverse()
# Output: 0 -> 1 -> 3

* String representation

• returns a string representation of the linked list.

Method:

• str()
