亚当数

给定数字n，编写程序检查给定数字是否为亚当编号。
亚当数是一个被反转的数字，该数字的平方和被反转的数字的平方应该是彼此相反的数字。最多1000的亚当数是：0、1、2、3、11、12、13、21、22、31、101、102、103、111、112、113、121、122、201、202、211、212， 221、301、311。

例子 ：

Input : 12
Output : Adam Number
Explanation: 
Square of 12 = 144
Reverse of 12 = 21
Square of 21 = 441
Now Square of 12 and square of reverse of 12 are 
reverse of each other. Therefore 12 is Adam number.

Input : 14
Output : Not a Adam Number

查找亚当编号的步骤：

Step 1:  Find square of number. 
Step 2:  Find reverse of number.
Step 3:  Find square of number in Step 2.
Step 4:  Find reverse of number in Step 3.
Step 5:  Find whether number obtained in Step 4 and Step 1 are equal or not.
