CHALLENGE ACTIVITY 3.1.3: 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 : 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. 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. Code writing challenge activity demo 4619942694856.93zqy7
