Java – ADAM Number

ADAM Number: Take a number then square it then reverse it then find its square root then reverse. If the given number equals to the final number then it is called ADAM.

• Take the number (12)
• Square the number (144)
• Reverse the number(441)
• Square root of number (21)
• Reverse the number(12)
