15. Book

Exercise Notes / Advice

See the build-image tutorial. Use that to do 15.3.3 and 15.3.{7-10}. Do not use build3-image even though the book says to use it. The build-image function is better.

• 15.3.4: The first input is the candidate for whom you are counting votes. (For example “Clinton”.) The next four inputs are votes cast for a person. (For example “Trump” “Clinton” “Sanders” “Trump”.) You are supposed to return the number of votes for the candidate from the first input. (For example: 1 in this case.)

• 15.3.7: Keep using build-image not build3-image.
