## What It Is

For example, the function should return 5 for linked list `[1 -> 3 -> 1 -> 2 -> 1]`

METHOD 1 (Iterative Solution)
--------------------------

* 1) Initialize count as 0 
* 2) Initialize a node pointer, current = head.
* 3) Do following while current is not NULL
     a) current = current -> next
     b) count++;
* 4) Return count 

> * Input: Linked List = `[1 -> 3 -> 1 -> 2 -> 1]`
> * Output: count of nodes is `5`
