Coding Review

Which of the following is an example of an algorithm?

• the weight of a package of macaroni and cheese in ounces

• directions for heating a package of macaroni and cheese in three steps

• a description of the ingredients of macaroni and cheese

• the cost of a package of macaroni and cheese in dollars

Writing an algorithm is most useful for a task that

• will need to be completed only once

• will need creativity to complete

• will need continued research to complete

• will need to be completed many times.

Which of the following tasks would you most likely use an algorithm to complete?

• convincing your neighbors to come with you to the pool

• imagining a new way to jump off the diving board that no one has done before

• following directions from your neighborhood to the swimming pool

• winning a treading water contest by reading water without getting tired

When you're using an algorithm to solve a problem, you are

• following steps exactly as they are written.

• coming up with a unique solution that works sometimes.

• make a solution more efficient

• making an inference using your prior knowledge.
