Write a program that reads an integer (greater than 0) from the console and flips the digits of the number, using the arithmetic operators / / and %, while only printing out the even digits in the flipped order. Make sure that your program works for any number of digits and that the output does not have a newline character at the end.

const stdin = process. openStdin ();

const stdout = process. stdout;

const reverse = input = > { / /checks if input is number

if (isNaN (parseInt (input))) {

stdout. write ("Input is not a number");

}

if (parseInt (input) < = 0) {. / / checks if no. is positive

stdout. write ("Input is not a positive number");

}

let arr = []; / / pushing no. in array

input. split (""). map (number = > {

if (number % 2 = = 0) {

arr. push (number);

}

});

console. log (arr. reverse (). join ("")); / / reversing the array

};

stdout. write ("Enter a number: ");

let input = null;

stdin. addListener ("data", text = > {

reverse (text. toString (). trim ()); / /reversing

stdin. pause ();

});

Explanation:

In this program, we are taking input from the user and checking if it is a number and if it is positive. We will only push even numbers in the array and then reversing the array and showing it on the console.
