$4\mathrm{.}23$: Basic while loop expression.

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 $=40$ :

$20,10,5,2,1$

Note: These activities may test code with different test values. This activity will perform four tests, with userNum $=40,$ then with userNum $=2,$ then with userNum $=0,$ then with userNum $=-1.$ See "How to Use zyBooks"

Also note If the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "Program end never reached" The system doesn't print the test case that caused the reported message.
