Question

Write a program in java 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

Question:-

➡ Write a program in Java to display all the Automorphic Numbers from 1 to 2000.

Program:-

class Automorphic

{

static boolean isAutomorphic(int n)

{

int c=0, a=n, b=a*a;

while(a!=0)

{

c++;

a/=10;

}

return (n%(int)Math.pow(10,c)==b);

}

public static void main(String s[])

{

System.out.println("Automorphic Numbers from 1 to 2000 are..");

for(int i=1;i<=2000;i++)

{

if(isAutomorphic(i))

System.out.print(i+" ");

}

}// main()

}// class.
