How do you add a node after a position P in singly linked list?

Algorithm

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

How node is inserted in the middle position in linked list?

Steps to insert node at the middle of Singly Linked List. Means the new node should also point to the same node that the n-1th node is pointing to. (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.

How do you add a linked list in C++?

60 second clip suggested5:52Linked List – Insert Node at beginning or end using C++ – YouTubeYouTubeStart of suggested clipEnd of suggested clipIn a head pointer pointing to the first node. And we want to insert a new node with value 1 in theMoreIn a head pointer pointing to the first node. And we want to insert a new node with value 1 in the beginning of the linked list. So we create a new node using the new operator.

What are the ways to insert a node in linked list?

Insert Elements to a Linked List

  1. Insert at the beginning. Allocate memory for new node. Store data. Change next of new node to point to head.
  2. Insert at the End. Allocate memory for new node. Store data. Traverse to last node.
  3. Insert at the Middle.

How do you insert a node in a specific position in a doubly 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 TEMP = START.
  6. Step 6: SET I = 0.
  7. Step 7: REPEAT 8 to 10 until I.
  8. Step 8: SET TEMP = TEMP -> NEXT.

How do you add a node to a specific position in a linked list C++?

Insert a node at a specific position in a linked list

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

How do you insert a node in the nth position?

Insert a Node at Nth Position

  1. If Head is null and position is not 0. Then exit it.
  2. If Head is null and position is 0. Then insert new Node to the Head and exit it.
  3. If Head is not null and position is 0. Then the Head reference set to the new Node.
  4. If not, iterate until finding the Nth position or end.

Can you insert into the middle of a singly linked list?

Can you add to the middle of a linked list?

Given a linked list containing n nodes. If n is even, then insert the new node after the (n/2)th node, else insert the new node after the (n+1)/2th node. …

How do you traverse a doubly linked list in C++?

Traversing is the most common operation in case of each data structure. For this purpose, copy the head pointer in any of the temporary pointer ptr. then, traverse through the list by using while loop.
