Automorphic Number.

-

Program to check whether a given number is Automorphic number or not.


A number is said to an automorphic number if its "square" ends with the same digits as the number itself.
for example, 5, 6, 76, 376 etc are automorphic number as its square are 25, 36, 5776, 141376 and 5, 6, 76, 376 are present as the last digits.







SOURCE CODE


import java.io.*;
public class Automorphic
{
    public static void main(String args[])throws IOException
    {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        System.out.print("Enter a number    :");
        int a=Integer.parseInt(br.readLine());
        int sq=a*a;
        int rem,n=a,j=1;
        while(n>0)
        {
            rem=n%10;
            n=n/10;
            j*=10;
        }
        if(sq%j==a)
        System.out.println("Yes, it is an Automorphic No.");
        else
        System.out.println("No, it is not an Automorphic No.");
    }
}
