Automorphic Number

Automorphic Number
---------------------------
Given a number N, the task is to check whether the number
is Automorphic number or not.

A number is called Automorphic
number if and only if its square ends in the same digits as 
the number itself.

Examples :
Input  : N = 76
Output : Automorphic
Explanation: As 76*76 = 5776

Input  : N = 25
Output : Automorphic
As 25*25 = 625

Input : N = 7
Output : Not Automorphic
As 7*7 = 49
