What happens when you set start outside of a while loop?
When you set startup outside of your initial loop, you’re guaranteeing that you’re getting the wrong time it takes for the while loop to execute. It would be like saying: this is because the start remains static throughout the execution time, while the end time is constantly increasing over time.
