Imagine that you are a bus driver. You stop at a traffic light and see your friend Harry crossing the road. While the light is red, you greet your friend, and yell: Hey Harry! The light turns green once you greet each other, and you must keep driving.
Interpret this scenario using the while loop. Create a variable isRed and set the initial value to true. Display the message Hey Harry! inside the loop, and then, when the light goes green, change the value of the isRed variable.
