Detect loop in a linked list

Generally in singly linked list last node pointer fields are contain NULL value. That NULL value indicate end of linked list.

If In a case this last node pointer fields are not NULL. So this last node next pointer fields are store the address of other node of linked list. Suppose that this pointer are storing the address of existing linked list node. In this situation linked list contain loop. So our goal are is to detecting loop in given single linked list.

Suppose we are inserted the following (1,2,3,4,5,6) node in a sequence.

Here given code implementation process.
