For the 101, I am not sure as to how we are suppose to complete the exercises. I notice that there is code written below the instructions of each exercise. Is this code supposed to be the solution or a hint? If so, while completing these 101 exercises are we meant to erase what is on the bottom and re do the exercise while not looking at what is written on the bottom or are we supposed to use what is written on the bottom as a hint to completing the solution?
