    Do the following exercise in DrRacket on your own or in pairs (using the ideas in the Pair Programming article):
  • Exercise 13.7.5 from the textbook [Show ALL Design Recipe steps including Data Analysis and 5 well-chosen examples. For full credit, you must type your function definition from 13.3.3 in HW8 into the Definitions Pane and then "re-use" it in the function body to 13.7.5, using the ideas of Chapter 11.]

    Do the following exercises in DrRacket on your own or in pairs (using the ideas in the Pair Programming article):
  • Exercise 15.3.1 from the textbook
  • Exercise 15.3.2: Modify your solution to Exercise 15.3.1 to produce the string "Out of stock!" if the input isn't any of the known games (instead of the picture of a question mark mentioned in the text). [Name this function choose-picture-v2 so that you do not comment out the function for 15.3.1. No need to redo the whole Design Recipe, since you did it for 15.3.1. Just copy the examples, change the function name to choose-picture-v2, and add a test case or two for the condition you are adding. Make sure to fully test choose-picture-v2?.]
  • Exercise 15.3.6 from the textbook
  • EXTRA CREDIT (20 points): Exercise 5.1.5 in How to Design Programs: First Edition. [Replace all the symbols by strings in the exercise. Skip the last 3 lines involving the master.ss teachpack.]
