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 $=40$:$2010521$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 $=-1$
