T>You are assigned to develop a system that will classify skiing and mountain biking trails according to their difficulty. There are three difficulty ratings: Easy, Intermediate, and Advanced. Use the HtDD recipe to design a data definition to represent trail difficulty ratings (call it Difficulty) The difficulty rating of a trail is often represented visually by a coloured shape. Easy trails are indicated by a green circle, intermediate trails by a blue square, and advanced trails by a black diamond. Design a function called trail-symbol that takes a Difficulty and produces an image of the symbol used to represent it. Hint: you may want to use the built-in function rhombus. A pet supply store categorizes dogs into sizes based on weight. There are 3 weight categories corresponding to 3 sizes: Dogs weighing under 15.5 kg are considered small. Dogs weighing 15.5 to 30 kg are considered medium. Dogs weighing more than 30 kg are considered large. Use HtDD to design a data definition for a dog's weight (call it Weight). Use HtDD to design a data definition for a dog's size (call it Size). Design a function that takes a dog's weight and produces the corresponding size according to our description in problem 3.
