More Information

Quick-Start Guide

What's the least I need to know to use the competition arena?

There's a lot of important information in the official Terms and FAQ for Google Code Jam; and if you're competing, you should read them. But if you're on the site to practice your programming skills, or you just need a quick refresher on how the competition arena works, here are the steps you should follow:

  1. Open the competition arena to your round. [+]
  2. Read the problem. The first few sections will describe precisely what problem your program needs to solve. [+] Take careful note of the Limits section. This section will describe two different sets of limits: limits for the Small input and the Large input. This should give you some idea of how quickly your algorithm will need to run.
  3. Write a program that will solve the problem described, with the Small limits described, in less than ~3 minutes. Make sure your program accepts input and gives output in the format given; if you run it with the Sample Input as input, it should produce precisely the Sample Output (including the "Case #" text).
  4. At the top of the page, click to solve the small and download the input. During a real contest, a 4-minute timer will start as soon as we receive the download request. If you're practicing, there won't be a timer (but your code should still be able to solve the problem in 4 minutes).
  5. Run your program on that input, and save the result in a file. Submit that file as your output, and your source code as your code.[+] The server will respond in one of a few ways:If you run out of time before making a submission, it will be treated in the same way as if you submitted and were incorrect.
    1. Correct: Your submission was completely correct in every case!
    2. Rejected: The response should tell you what was wrong; often it means you submitted the wrong file. The clock is still ticking, so see if you can fix the bug before you run out of time.
    3. Incorrect: Your result was wrong, maybe even in just one test case. You can fix your program and try again as many times as you like. [+] You'll download a new input file every time, so don't use the old one again by mistake! [+]
  6. After you solve the Small input, the Large input will become available. Once your program is ready to deal with the higher limits, download the Large input. An 8-minute timer will start as soon as we receive the download request.
  7. Run your program and submit as with the Small. You won't know whether you solved the problem correctly until the end of the competition, though your submission could be rejected. [+] We won't stop the timer after you submit, so if you want to do some testing and submit again, you can do that. You'll only be judged on your last submission.
  8. Move on to another problem (there's a list on the left). Each input you solve correctly is worth a number of points that's written next to its download link; the contestant with the most points at the end of the contest wins. Ties are broken by which contestant got her last point first, with 4 minutes of penalty time given for each incorrect submission on a small input that you got right later.

You may choose to use your own keyboard and other materials permitted by Google. Google will send you a list of permitted materials by email at least 7 days before the beginning of the final round.
  4. 4. Problems.
    1. 4.1 Editor; Programming Language; and Compiler.
      1. (A) Editors. You may use any editor or development environment, including those made available online as long as your code is not accessible to others.
      2. (B) Programming Language and Compiler. For the qualification round of Code Jam, you may use any programming language to solve a Code Jam problem. However, for any round after the qualification round, the compiler or interpreter you use must be available such that anyone else can use it for free without a time limitation and without violating any rights of any person or entity, except that the following are permissible:
        1. (1) Visual Studio, Microsoft Excel, and MATLAB;
        2. (2) compilers and interpreters that require Microsoft Windows or Mac OS X, as long as the compiler or interpreter itself is free, as described in this Subsection (B); and
        3. (3) any further exceptions that Google may communicate to you by email or on the Contest website.
    2. 4.2 Submitting Solutions for Code Jam Problems. For Code Jam problems, you must submit through the Contest website a correct output file and the source code used in its generation or a written explanation explaining how you solved the problem.
      1. (A) Submission Requirements. You must submit source code as one or more plaintext or zipped plain text files. The size of each source code file may not exceed 100KB, and the total size of your source code for an output after being unzipped may not exceed 1MB. If you use a standard library that is freely available on the Internet that is too large to include in your submission, you may exclude it as long as you put a comment in your source code explaining where the library is available.
      2. (B) Time Limit. When you attempt to solve a particular input for a Code Jam problem, a timer will start as soon as you begin downloading the file. You must submit your solution in accordance with Subsection (A) above within:
        1. (1) 4 minutes for a small input;
        2. (2) 8 minutes for a large input; or
        3. (3) some other time as specified in the problem for other inputs, but in each case no later than the end of the round of the Contest.
      3. (C) Small Inputs. In Code Jam, Google will judge your submissions for small inputs immediately and notify you if your submission is correct or incorrect. If the output file and source code file are not received by the end of the 4 minute period or if the output you submit is judged incorrect, you may choose to attempt to solve that problem again within the time remaining in the round, but will have to download a new small input.
      4. (D) Large Inputs. In Code Jam, you can only attempt to solve each large input once. For each large input, you can make multiple output submissions within the 8 minute period, but only your last submission will be judged. Google will notify you whether your submission was correct or incorrect after the round ends by posting the results on the Contest website.
      5. (E) Submission Errors and Discrepancies.
        1. (1) During a Round. Google may ignore certain incorrect submissions in Code Jam and notify you that the submission was malformed and that you may submit again in whatever time remains in the period. During a round of Code Jam, if you think you submitted the wrong source code for an output, you may notify the judges using the "Ask a Question" link on the Contest website. For inputs other than large inputs, the judges may mark the submission as incorrect so that you can attempt the problem again. For a large input for onsite rounds of Code Jam, the judges may, in their discretion, permit resubmission of the source code.
        2. (2) After a Round. You may not submit source code for any round after it ends. After the end of a round, if a discrepancy is discovered between the output file you submitted that was judged correct and the corresponding source code that you submitted, then a panel of two or more judges consisting of employees of Google will examine the source code for your submissions. The judges will determine whether a discrepancy exists, and if so will decide in their sole opinion whether the discrepancy is trivial or non-trivial. For a trivial discrepancy, you will be assessed a 4-minute penalty for that input. For a non-trivial discrepancy, you will be assessed a 4-minute penalty in a qualification round and you will forfeit all points for that input in all other rounds.
    3. 4.3 Submitting Solutions for Distributed Code Jam Problems. For Distributed Code Jam Problems, you must submit through the Contest website the source code for your solution and it will be compiled and run on Google Compute Engine. The Contest website will return a response code indicating whether your solution was accepted or not. The Contest website will provide a list of response codes and their meaning.
      1. (A) Submission Requirements. Your solution for a problem in Distributed Code Jam must be a single file of source code written in one of the approved languages listed on the Contest website which may list additional requirements for a particular language. Your solution:
        1. (1) cannot exceed 100KB in size;
        2. (2) must compile to 4MB or less in size;
        3. (3) must compile in less than 10 seconds under 64-bit Linux;
        4. (4) cannot fork or create threads;
        5. (5) cannot replace the currently executed binary with a different one (e.g. you cannot use exec);
        6. (6) can only use the libraries published on the Contest website;
        7. (7) cannot embed assembler code;
        8. (8) cannot use network functions (you must use the library published on the Contest website to communicate with other instances);
        9. (9) cannot open files (including temporary files);
        10. (10) cannot violate system security;
        11. (11) cannot wait for user interaction;
        12. (12) cannot use more memory than specified in the problem statement; and
        13. (13) must make all instances exit with a 0 exit code.
      2. (B) Time Limit. You must submit your solutions for problems in Distributed Code Jam within the round and your solutions must compile and run within the time specified in the problem, the Contest website, and these Terms (with precedence given in that order).
      3. (C) Small Inputs. In Distributed Code Jam, you must provide a correct solution for the problem's small input before you can solve the large input. If your solution was not accepted, you may continue to submit new solutions for the small input until it is accepted or until the round expires.
      4. (D) Large Inputs. Within a round of Distributed Code Jam, you can submit more than one solution for a large input, but only your last submission will be judged. Google will notify you whether your submission for the large input was correct or incorrect after the round ends by posting the results on the Contest website.
      5. (E) Test Runs. You may submit test runs in Distributed Code Jam. The Contest website will provide more information on how to submit a test run and how often you may submit them.
    4. 4.4 Penalty Time. Your penalty time for a round in Code Jam or Distributed Code Jam is equal to the time it took you to submit your last correct solution measured from the start of the round, plus 4 minutes for each incorrect solution you submitted for small inputs you eventually solved. Penalty times may also be specified in a problem statement.
  5. 5. Attendance at the Final Round and Related Events.
    1. 5.1 Required Attendance. You should arrive in New York City at least one day in advance of the final round to avoid being late and possibly disqualified.
