Exercise: Matching Contracts and Examples

Directions: Match each Example on the left with the Contract on the right. NOTE: Multiple examples may match to the same contract!

(EXAMPLE (match 30 "red") (+ 30 (string-length "red")))
; match : image -> image
(EXAMPLE (match 10 "blue") (+ 10 (string-length "blue")))
; match : number string -> number
(EXAMPLE (match (triangle 20 "solid" "blue") 3) (scale 3 (triangle 20 "solid" "blue")))
; match : number image -> image
(EXAMPLE (match (circle 10 "solid" "orange") 22) (scale 22 (circle 10 "solid" "orange"))
; match : number -> image
(EXAMPLE (match 5 (star 20 "solid" "red")) (rotate (- 90 5) (star 20 "solid" "red")))
; match : image number -> number
(EXAMPLE (match (circle 20 "outline" "gold")) (rotate 37 (circle 20 "outline" "gold")))
; match : image number -> image
(EXAMPLE (match (circle 10 "solid" "green")) (rotate 37 (circle 10 "solid" "green"))
(EXAMPLE (match 30) (star (* 30 2) "outline" "purple"))
(EXAMPLE (match (circle 10 "solid" "silver") 16) (* 16 (image-height (circle 10 "solid" "silver"))
