00:00 – Insertion at beginning of linked list
01:42 – Pseudo code

In this video, discussing about how to add the element at beginning of linked list. This is to be explain with the help of source code and example. I hope this video is helpful to you.

Code for execution:
class Node:
def __init__(self, data):
self.data = data
self.next = None
# Creating nodes
node1 = Node(10)
node2 = Node(20)
node3 = Node(30)
node4 = Node(40)
# Connecting nodes
node1.next = node2
node2.next = node3
node3.next = node4
# Adding a new node at the beginning
head=node1
new_node = Node(50)
new_node.next = head
head = new_node
