22a. Recursion Self Quiz
A brief quiz to make sure you understand recursion.
draw-cats: string -> image
Draw one cat for every time the word “cat” appears in the string.
(draw-cats "nyan cat")
(draw-cats "cat dog cat")
note
I have had problems with tests failing even though the images are identical. I found that scaling the image in Racket caused the problem. Now I do notscale the size of the images I use in my tests.
