Find length of Doubly Linked List

This is basic problem how to count length of doubly linked list. We can solve this problem using by linked list traversal.

Process: Use one counter integer variable, and use one Linked list pointer which that is point to front node of linked list. and iterate one by one nodes of this linked list and increment counter value one by one. When this pointer are NULL then stop execution process and display counter value. Time complexity of this process are O(n). n is number of linked list nodes.

Suppose we are inserted the following (4, 3, 2, 5, 3) node in a sequence.

Here given code implementation process.
