Write an expression that executes the loop while the user enters a number greater than or equal to $0.$

Note: These activities may test code with different test values. This activity will perform three tests, with user input of $9,5,2,-1$; then with user input of $0,-17,$ then with user input of $010-1.$ 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 "Test aborted."
