Answer 1

Automorphic Number:-

An automorphic number is a number whose square "ends" in the same digits as the number itself.

Code:-

1. class Automorphic
2. {
3. public static void main (int n)
4. {
5. int m=n;
6. int squ=n*n,j=1;
7. for(;m>0;m=m/10)
8. {
9. j=j*10;
10. }
11. if((squ%j)==m
12. System.out.println("Automorphic Number");

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• Write a program to check whether a number is automorphic number or not.

$\star\:\:\:\bf\large\underline\blue{Source\:Code:-}$

• A number is said to be automorphic number if the square of the number ends with the same digits as the number has. Examples of automorphic number are 1,5,6,25 625 and so on.

class IfAutomorphic {

public static void main(int n) {

int s=n*n;

String s1=Integer.toString(s),s2=Integer.toString(n);

if(s1.endsWith(s2) )

System.out.println("Automorphic Number. ");

else

System.out.println("Not an Automorphic Number.");

}

}
