SuperPalindrome Number in JAVA

Super Palindrome Number

Super Palindrome Number: A Super Palindrome Number is a Palindrome Number whose square is also Palindrome.

Example:

Input         : 11

Square      : 11 X 11 = 121

Output     : It is a Super Palindrome Number

Input         : 22

Square      : 22 X 22 = 484

Output     : It is a Super Palindrome Number

Input         : 44

Square      : 44 X 44 = 1936

Output     : It is not a Super Palindrome Number

 

Algorithm and Program given below :-

Algorithm :-

1. Get the number to check for palindrome.

2.   Hold the number in another variable

3.   Calculate and store the square of the number

4.   Check if the number is palindrome or not

5.   If it is not palindrome print “It is not a Palindrome Number”

6.   Else Check if the square is palindrome or not.

7.   If the square is palindrome print “It is a SuperPalindrome Number”

8.   Otherwise print “It is not a SuperPalindrome Number”.

9.   Compile and Run the Program.

 

Program :- 

import java.io.*;
import java.util.*;
class SuperPalindrome
{
    public static void main(String args[])
    {
        Scanner in= new Scanner(System.in);
        int n,p,sq,x,rev,s=0,res,sum=0;
        System.out.println("Enter No.");
        n= in.nextInt(); // Input number from user
        p=n; // store the entered number in "p" variable
        sq= n*n;
        x=sq;
        while(n>0)
        {
            rev=n%10; // extract last digit of the number
            s=s*10+rev; // store the digit last digit
            n=n/10; // extract all digit except the last
        }
        if(p==s) // Checking if the number is Palindrome or not
        {
            while(sq>0)
            {
                res=sq%10;
                sum=sum*10+res;
                sq=sq/10;
            }
            if(sum==x)
            {
                System.out.println("It is a SuperPalindrome Number : "+p);
            }
            else
            {
                System.out.println("It is not a SuperPalindrome Number : "+p);
            }
        }
        else
        {
            System.out.println("Number is not Palindrome : "+p);
        }
    } // end of main method
} // end of class
