Answer 2

Question:

Write a program to check the number is neon or not.(java)​.

Answer:

import java.util.*;

public class NeonNumber  

{

public static void main(String[] args)

{

int n,s,sum=0;

Scanner in = new Scanner(System.in);

System.out.print("Enter the number: " );

n=in.nextInt();

s=n*n;

while(s>0)

{

sum=sum+s%10;

s=s/10;

}

if(sum==n)

System.out.println("Its a Neon number.");

else

System.out.println("Its not a Neon number.");

}

}

Explanation:

A neon is that in which the sum of the digits of the square of the number is equal to the number.

For example:

Let's say a number, 9.

The square of 9_

(9×9)

= 81

The sum of the digits of the square of 9_

(8+1)

= 9

Hence,

9=9.

∴ 9 is a neon number.
