For everyone who want to know how to solve my Quizz using the brute force code,
See @Hatsy Rei Code.
its cool how code solve code.

@kshitiz
i will rename the variable so it is human friendly
var x,
xx,
y,
z,
xxx = parseInt(document.getElementById('ANID').value, 10);
/* user input because variable xxx take input from user
(datatype is string even if you type in a number)
then convert it to integer.
*/
x = (xxx == xxx);
// variable x is true (remember boolean)
x = (++x*x*x+x);
/* since x is true than its value is 1
so (++1*2*2+2) is 10
++1 is 2 (preincrement)
*/
xx= (xxx%x)*(xxx%x);
y = (x/x)+(x/x);
z = (x/y);
y = (y*y*y);
z = (z*z*z);
y = (y*y*y);
z = (z*z*z);
x = y*z - xx/xx;
if ((xx*xxx) == x){
alert("Yes, You are right !!!")
} else {
alert("Miouwww,Try again!")
}
}

@jafca, do you know the answer?

@jafca, is my equation correct??

Great, let me learn some maths then 😅😅

Cyrus, How did you do that? 😅😅

Answer will be 8 digit number and the last digit is (Input % 10). And the equation was :
input * ((input % 10) ^ 2) = 999,999,999
so, input = 999,999,999 / (last digit of the input ^ 2)
On my calculator I entered 999,999,999 / (9 * 9) and it showed 12345679. Was right in first guess.

I thought the same but stuck somewhere 😅
anyway great

@Adi
your knowledge is larger than me in IT.
i just start programming february this year.
thanks to Sololearn i can write code in different languages.
at first i only know basic html and php.

@Cyrus You may want to hide your equation. It's correct now. @Sachin hid his 😀
p.s. the calculation is surprisingly easy. Don't overthink it 👍

wow @Cyrus 😂😂😂

@Cyrus
You are younger than me, so with this fast development, i am sure you will outsmart me in the future.
keep learning.😃

@Cyrus Your equation is wrong...

@Sachin Misread you equation. Keep going 👍
And yes, I do... It's almost a nice number

@Sachin Yes, if I remember correctly 😄
