Linked List | Set 2 [Inserting a node]
We have introduced Linked Lists in the previous post. We also created a simple linked list with 3 nodes and discussed linked list traversal.
All programs discussed in this post consider the following representations of linked list.
|
// A linked list node
class Node
{
public:
int data;
Node *next;
};

|
|
// A linked list node
struct Node
{
int data;
struct Node *next;
};
|
|
// Linked List Class
class LinkedList
{
Node head; // head of list
/* Node Class */
class Node
{
int data;
Node next;
// Constructor to create a new node
Node[int d] {data = d; next = null; }
}
}
|
|
# Node class
class Node:
# Function to initialize the node object
def __init__[self, data]:
self.data = data # Assign data
self.next = None # Initialize next as null
# Linked List class
class LinkedList:
# Function to initialize the Linked List object
def __init__[self]:
self.head = None

/* Linked list Node*/
public class Node
{
public int data;
public Node next;
public Node[int d] {data = d; next = null; }
}
|
|
// Linked List Class
var head; // head of list
/* Node Class */
class Node {
// Constructor to create a new node
constructor[d] {
this.data = d;
this.next = null;
}
}

In this post, methods to insert a new node in linked list are discussed. A node can be added in three ways
1] At the front of the linked list
2] After a given node.
3] At the end of the linked list.
