EXERCISE 5: This program has 3 different functions that are almost the same. Let's refactor it to use one function!

• Create a Custom Block and store the four lines of code under fly_high() within it (lines 6-9).
• Create a function and name it fly with two parameters: the integer fly_height to control how high the toucan flies and the string fly_type to control what the toucan says.
• Use the new function to have the toucan do the same series of flights as before: high, high, low, medium, low.
