Insertion and Deletion of Elements In Python, you can insert elements into a list using .insert() or .append(). For removing elements from a list, you can use their counterparts: .remove() and .pop(). The main difference between these methods is that you use .insert() and .remove()...
# Linked list operations in Python # Create a node class Node: def __init__(self, data): self.data = data self.next = None class LinkedList: def __init__(self): self.head = None # Insert at the beginning def insertAtBeginning(self, new_data): new_node = Node(new_data) new_...
Inserting and deleting a node at the beginning of a singly-linked list is highly efficient with a time complexity of O(1). However, insertion and deletion in the middle or at the end requires traversing the list until that point, leading to an O(n) time complexity. ...
Add a node of value val before the first element of the linked list. After the insertion, the new node will be the first node of the linked list. """ self.addAtIndex(0, val) defaddAtTail(self,val:int)->None: """ Append a node of value val to the last element of the linked ...
We have only covered three basic linked list operations above: traversal (or search), node deletion, and node insertion.There are a lot of other operations that could be done with linked lists, like sorting for example.Previously in the tutorial we have covered many sorting algorithms, and we...

Implement these functions in your linked list class: get(index) : Get the value of theindex-th node in the linked list. If the index is invalid, return-1. addAtHead(val) : Add a node of valuevalbefore the first element of the linked list. After the insertion, the new node will be...
This article will explain insertion sort for a doubly-linked list; moving on, we will see its algorithm in detail with itsC++code, and at last, we will see its space and time complexity. First, we need to know what a doubly-linked list is?
