Question of the Day: AP Computer Science A

Which is more efficient (i.e. Lower Big O)?

1)

arr = [1, 2, 3, 4, 5, 6, 7, 8]

arr2 = [[1,2],[3,4],[5,6], [7,8], [9,10], [10, 11]]

for (int i = 0; i < arr.length; i++) {

    for (int j = i; j < arr2.length; j++) {

         arr[i][j] = 0;

    }

}

 

2) 

arr = [1, 2, 3, 4, 5, 6, 7, 8]

arr2 = [[1,2],[3,4],[5,6], [7,8], [9,10], [10, 11]]

for (int i = 0; i < arr.length; i++) {

     for (int j = 0; j < arr2.length; j++) {

          arr[j] = 0;

     }

}

The Big O is equivalent

AP Computer Science A is similar to a foreign language in many ways. In order to understand the entirety of the subject, you must also know all the terms and their uses. This means computer science is a subject that should be studied on a daily basis in order to master the topic, regardless if you are just learning the topic or preparing to test for it. However, as you work toward taking the AP Computer Science examination, it’s especially important to focus on the subject on a daily basis in order to become as comfortable with it as possible. Through Varsity Tutors’ Learning Tools, you can find the Question of the Day, which can help you can get a mini-AP Computer Science A review on a different topic each day, allowing you to keep your mind focused on the subject matter as you prepare for your test.

The AP Computer Science A Question of the Day is set up in a format that’s similar to the actual test, in that the topics and types of questions are the same as the ones covered on the AP test. Because of this, you can familiarize yourself with the types of questions and formats that you will see, which can be very helpful to you as you move toward test day. Each time you use the Question of the Day Learning Tool, you will receive a question with several multiple-choice answers to select from, allowing you to think critically about the options before selecting the answer you believe to be the correct one.

Once you have answered, the Question of the Day will provide you with the correct answer, as well as a number of statistics to help you understand the answer. Beyond the answer itself, the results page provides statistics that can help enhance your learning experience. Among the statistics that you will receive include the percentage of other students who also answered the question correctly, as well as the time it took them and you to answer each question. These statistics can be integral to your AP Computer Science review, as they will show you where you match up against other prospective test-takers, as well as the speed at which you are able to answer the questions provided. These can be key assets as you prepare for the examination, as they will show you the areas where you have room for improvement.

The AP Computer Science A Question of the Day feedback goes beyond the review that the question and answer format provides by giving you clear explanations for each question’s answer. This can be extremely helpful as you strengthen your knowledge, as you will be able to understand not only the topic itself, but the “why” behind the answer. There are also links to relevant concepts, terms, and definitions, which can be particularly important when you face questions that are more difficult than others. All of the feedback for the AP Computer Science example questions will provide you an opportunity for more extensive understanding in each topic.

The AP Computer Science A exam, like any Advanced Placement test, is not one to be taken lightly. Anyone who takes it should plan to undergo extensive review. With the help of Varsity Tutors’ Learning Tools, including the Question of the Day, you will get a daily AP Computer Science review using the type of questions you will face on the day of your test. When you use the Question of the Day along with the other Learning Tools, you are working to be as prepared as you can be for your upcoming exam.
