In java, write a while loop that prints usernum divided by 2 (integer division) until reaching 1. follow each number by a space. example output for usernum = 20:

public class HelloWorld{

    public static void main(String []args){

        int userNum = 20;

        while(userNum!=1){

            userNum = userNum/2;

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

        }

    }

}

Explanation:

Create the main function and declare the variable userNum with value.

then, use a while loop and it run until the userNum not equal to one when it become equal to 1 the while loop terminate.

Inside the loop, divide the userNum by 2 and then assign to userNum and this process continue until condition  true.

for example:

userNum = 20

userNum =20/2=10

then, 10/2=5

5/2=1

after that condition false. and while loop terminate.
