# How do you insert at the end of the linked list?

## How do you insert at the end of the linked list?

The new node will be added at the end of the linked list….make the last node => next as the new node.

1. Declare head pointer and make it as NULL.
2. Create a new node.
3. If the head node is NULL, make the new node as head.

What is the way to insert a node in linked list?

Insert a node at a specific position in a linked list

• Traverse the Linked list upto position-1 nodes.
• Once all the position-1 nodes are traversed, allocate memory and the given data to the new node.
• Point the next pointer of the new node to the next of current node.

### How is an element inserted between two nodes in a linked list?

Traverse to the n-1th position of the linked list and connect the new node with the n+1th node. (newNode->next = temp->next where temp is the n-1th node). Now at last connect the n-1th node with the new node i.e. the n-1th node will now point to new node. (temp->next = newNode where temp is the n-1th node).

How do you insert at the beginning of a linked list?

Algorithm

1. Step 1: IF PTR = NULL.
2. Step 2: SET NEW_NODE = PTR.
3. Step 3: SET PTR = PTR → NEXT.
4. Step 4: SET NEW_NODE → DATA = VAL.
5. Step 5: SET NEW_NODE → NEXT = HEAD.
6. Step 6: SET HEAD = NEW_NODE.
7. Step 7: EXIT.

#### How insertion and deletion is done in linked list?

Basic Operations

1. Insertion − Adds an element at the beginning of the list.
2. Deletion − Deletes an element at the beginning of the list.
3. Display − Displays the complete list.
4. Search − Searches an element using the given key.
5. Delete − Deletes an element using the given key.

How do we insert a node at the end of a singly linked list?

Steps to insert node at the end of Singly linked list

• Create a new node and make sure that the address part of the new node points to NULL i.e. newNode->next=NULL.
• Traverse to the last node of the linked list and connect the last node of the list with the new node, i.e. last node will now point to new node.

## What is the ways to insert a node in linked list write an algorithm for inserting a node at first position?

Algorithm

• STEP 1: IF PTR = NULL.
• STEP 2: SET NEW_NODE = PTR.
• STEP 3: NEW_NODE → DATA = VAL.
• STEP 4: SET TEMP = HEAD.
• STEP 5: SET I = 0.
• STEP 6: REPEAT STEP 5 AND 6 UNTIL I.
• STEP 7: TEMP = TEMP → NEXT.
• STEP 8: IF TEMP = NULL.

How do you insert a node at the beginning of a linked list C?

Algorithm

1. Declare a head pointer and make it as NULL.
2. Create a new node with the given data.
3. Make the new node points to the head node.
4. Finally, make the new node as the head node.

### What are the ways of implementing linked list?

In C language, a linked list can be implemented using structure and pointers . struct LinkedList{ int data; struct LinkedList *next; }; The above definition is used to create every node in the list. The data field stores the element and the next is a pointer to store the address of the next node.
