Copy linked list in Java
Given a Linked list, Create a deep copy of Linked list. We will clone Linked list using below 2 approaches,
Recursive approach:
In this approach we will recursively create a new Node(clone node) in each recursive call and start assigning next pointer of each node when recursive call returns. Iterative approach:
In this approach we need to take care of cloned start node, initialy it will be null, and after creation of first node we will assign that node to cloned start node and preserve start node for returning back to caller. After creating cloned start node, we will create further Nodes iteratively and assign next pointer of previously created node to newly created node.

For keeping track of previously created node, we need to take one pointer which store reference of Node created in previous iteration.
