A number is called Automorphic number if and only if its square ends in the same digits as the number itself. For example, 25 is an automorphic number because its square (625) ends with 25.

Task

Given a positive number, determine if it is Automorphic or not. If it is, return "Automorphic", otherwise return "Not!!"

Examples

• 25 is an automorphic number, because $25^2=62525^2\; =\; 625$ ends with 25, so return "Automorphic".
• 13 is not an automorphic number, because $13^2=16913^2\; =\; 169$ does not end with 13, so return "Not!!".
• 76 is an automorphic number, because $76^2=577676^2\; =\; 5776$ ends with 76, so return "Automorphic".
• 225 is not an automorphic number, because $225^2=50625225^2\; =\; 50625$ does not end with 225, so return "Not!!".
• 625 is an automorphic number, because $625^2=390625625^2\; =\; 390625$ ends with 625, so return "Automorphic".
• 1 is an automorphic number, because $1^2=11^2\; =\; 1$ ends with 1, so return "Automorphic".
• 6 is an automorphic number, because $6^2=366^2\; =\; 36$ ends with 6, so return "Automorphic".
