What are some examples of linked lists in programming?

Linked lists are data structures that consist of nodes, where each node contains data and a reference to the next node. Examples include singly linked lists, doubly linked lists, and circular linked lists.

Can you explain how a singly linked list works?

Sure! A singly linked list consists of nodes where each node points to the next node in the sequence. The first node is called the head, and the last node points to null, indicating the end of the list.

What are the advantages of using linked lists over arrays?

Linked lists offer dynamic memory allocation, easier insertions and deletions, and can grow or shrink in size, unlike arrays which have a fixed size.

Can you give me a code example of a linked list in Python?

Certainly! Here's a simple implementation of a singly linked list in Python:

class Node:
    def __init__(self, data):
        self.data = data
        self.next = None

class LinkedList:
    def __init__(self):
        self.head = None

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