Adam Number is a number whose square of the number and square of it’s reverse are reverse to each other.
Example 1: 12. Here 122 = 144 and 212 = 441. We observe that the square of 12 and the square of it’s reverse i.e. 21 are reverse of each other. Thus 12 is an Adam Number.
Example 2: 13. Here 142 = 196 and 412 = 1681. Here the square of 14 and the square of it’s reverse i.e. 41 are not reverse of each other. Thus 14 is not an Adam Number.
