How do you display singly linear linked list in reverse order?

Algorithm

1. Create a class Node which has two attributes: data and next.
2. Create another class which has two attributes: head and tail.
3. addNode() will add a new node to the list:
4. reverse() will reverse the order of the nodes present in the list.
5. display() will display the nodes present in the list:

How do you traverse data in a linked list in forward and backward direction write the algorithm?

Iterative Method

1. Initialize three pointers prev as NULL, curr as head and next as NULL.
2. Iterate through the linked list. In loop, do following. // Before changing next of current, // store next node. next = curr->next. // Now change next of current. // This is where actual reversing happens. curr->next = prev.

How do you reverse the linked list of size n?

Steps

1. Set pointer h = head.
2. Reverse the First K nodes of the Linked List using the 3 Pointer method.
3. h now points to the last element of the above K size Linked List reversed in the previous step.
4. Then Set h->next = reverse(n,k).
5. Return the pointer to the Kth node in the original Linked List.

How do you implement a singly linked list in C++?

This is given as follows. struct Node { int data; struct Node *next; }; The function insert() inserts the data into the beginning of the linked list. It creates a new_node and inserts the number in the data field of the new_node.

How can we print data from linked list?

Take two pointers to traverse the two linked lists using two nested loops. The outer loop points to the elements of the first list and the inner loop point to the elements of the second list respectively. In the first iteration of outer loop, the pointer to the head of the first linked list points to its root node.

Can we traverse back in singly linked list?

On a single-linked list, you can just reverse the links, then reverse-iterate while reversing the links again. The beauty of it is it stays O(n) in computing, and O(1) in memory.

Can we reverse singly linked list?

It doesn’t look possible to reverse a simple singly linked list in less than O(n). A simple singly linked list can only be reversed in O(n) time using recursive and iterative methods. A memory-efficient doubly linked list with head and tail pointers can also be reversed in O(1) time by swapping head and tail pointers.

How do you find the size of a linked list?

size() method is used to get the size of the Linked list or the number of elements present in the linked list.

1. Syntax:
2. Parameters: This method does not take any parameter.
3. Return Value: This method returns the size or the number of elements present in the LinkedList.
