Directions: Example 3.9.3 Rainbow Octagon As you explore this example, test out the following:  Rewrite this program using a function. o The original program uses 26 lines of code (excluding comments and blank space.) How much more efficient is your program? o Do you feel the program is easier to read and follow with or without the added function? Explain.  Change the pensize to 50. What do you notice about the ends of the lines Tracy draws?Challenge: Alter the program so the inside of the octagon is colored in cyan, as shown below:
