## Find the middle of a given linked list data structure

Question: In given a Linked List, find the middle of the list and print the number. Input : -> 4-> 2-> 7-> 9-> 1 Output : 7 Before starting you have to must know about Linked list and how to create it and Inserting node (data) in LinkedList. There is many approach to find middle number Read More…

## Inserting a new node in a linked list data structure

Inserting new node in linked list can do 3 ways. At start of Linked list In the middle of Linked list At the end of Linked list Before starting you have to must know about Linked list and how to create it. 1. At Start of Linked list

## Find Length of a Linked List data structure (Iterative and Recursive)

How to Find Length of Linked List data structure? Linked list A linked list is a linear data structure where each element is a separate object.Counting a node in linked list is important in programming when we are using linked list data structure. It will help you solve many problems like fining nth node from Read More…
