Write a menu driven program to accept a number from the user and check whether it is a Buzz number or an Automorphic number. i. Automorphic number is a number, whose square's last digit(s) are equal to that number. For example, 25 is an automorphic number, as its square is 625 and 25 is present as the last two digits. ii. Buzz number is a number, that ends with 7 or is divisible by 7.

 import java.util.Scanner;

public class q20

{

    public static void main(String args[ ]) 

    {

        Scanner in = new Scanner(System.in);

        System.out.println("1. Buzz number");

        System.out.println("2. Automorphic number");

        System.out.print("Enter your choice: ");

        int choice = in.nextInt();

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

        int num = in.nextInt();

        switch (choice) 

        {

            case 1:

            if (num % 10 == 7 || num % 7 == 0)

                System.out.println(num + " is a Buzz Number");

            else

                System.out.println(num + " is not a Buzz Number");

            break;

            case 2:

            int sq = num * num;

            int d = 0;

            int t = num;

            while(t > 0)

            {

                d++;

                t /= 10;

            }

            int ld = (int)(sq % Math.pow(10, d));

            if (ld == num)

                System.out.println(num + " is automorphic");

            else

                System.out.println(num + " is not automorphic");

            break;

            default:

            System.out.println("Incorrect Choice ");

            break;

        }

    }

}
