Question

Write a program to display all the Automorphic Numbers from 1 to 2000​

Answer 1

Answer:

Write a program to display all the Automorphic Numbers from 1 to 2000. (Example: 6, 25) [Since 6 2 = 36 and in 36 last digit = 6; similarly, 25 2 = 625 and in 625 last two digits = 25] [Hint: In the square form of the number if the last part is equal to the original number then the number is termed as Automorphic Number.]

Answer 2

Answer:

package LabPrograms;

import java.util.*;

public class automorphic {

  public static void main(String[]args)

  {

   

   for(int i= 1; i<=2000; i++)

   {

    int square = 0;

    if(i%10== 1 || i%10 == 5 || i%10== 6)

    {

     square = i*i;

     String mainnum = String.valueOf(i);

     String squarenum = String.valueOf(square);

     int lenofsquarenum = squarenum.length()-1;

     int j,flag=0;

     for(j = mainnum.length()-1; j>=0; j-- )

     {

      if(mainnum.charAt(j) != squarenum.charAt(lenofsquarenum))

      {

       

       

       flag=0;

       break;

       

      }

      else

      {

       flag=1;  

       lenofsquarenum--;

      }

       

     }

     if(flag==1)

     {

     System.out.println(i);  

     }

     

    }

   }

  }

}
