Question

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 = 40:

20 10 5 2 1

In java

import java.util.Scanner;

public class DivideByTwoLoop {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
int userNum;

userNum = scnr.nextInt();

*insert code*

System.out.println("");
}
}
