Frequently Asked Questions

What can I do within this environment?
This environment allows you to visualize the problem set, submit solutions for the problems, ask questions to the jury, see all submissions with evaluation results, and the current contest ranking.

How should the program read its input data? How should the results of a program be written?
Input data is passed to the process standard input and results must be written to the standard output.

I tried to submit a solution and got the message "Program with an invalid extension"!
You have to submit the source code for your program. A submission gets accepted for evaluation only if it has a file extension corresponding to the one of the accepted languages for the contest.

What languages and compilers are currently available?
For this contest the analyzer accepts the following languages and uses the following compilers:

$languages
Language Compiler Version Command line Extension

What's the meaning of the evaluation messages?
The evaluation messages are as follows:

Accepted: your program passed all tests and is accepted as correct;
Compile Time Error: the system was not able to successfully compile your program; the compiler returned an error or warning;
Runtime Error: your program "crashed", i. e. it exited prematurely due to a run-time error;
Time Limit Exceeded: your program did not finish within the given amount of time;
Wrong Answer: your program run through one or more test cases without a run-time error but the output did not match the expected output;
Presentation Error: the output seems to be correct but it is not presented in the required format. Since it is not always easy to distinguish this message from the wrong answer message, it is only sent in obvious cases;
Invalid Submission: your submission does not comply with expected extensions; or attempt to submit without following the interface;
Output Limit Exceeded: your program generates an output too long for this problem; the limits are dependent on the test cases, but are usually low (limit is around 100KB);
Program Size Exceeded: your program is too long and will not be considered (limit is around 100KB);
Requires Reevaluation: for some reason your program has to be re-evaluated;
Invalid Function: your program violates a contest rule like calling non-standard libraries; it may be terminating with exit(1) or even return 1, or a similar construct indicating an error in execute.

There are any limits enforced by the judging system?
There are several limits that if reached will penalize you:

When I press the submit button nothing happens!
You must check the cache policy being used by your browser. Pages should be retrieved from the server every time some update to the page is detected. If the pages are never requested from the server, they will not be updated in your browser. In Mozilla and Netscape check the "Edit" | "Preferences." | "Advanced" | "Cache" menu and choose "Every time (I view the page)".

The format of the interface has an odd appearance
Try choosing a smaller font ("Edit" | "Preferences." | "Appearance" "Fonts" ). Alternatively, try to remove the navigation and personal bars in the browser (menu "View").

I pressed the "Submit" button and got the message "Unspecified Program".
You must select the file with the source program. Press "Browse...." to open a file selection box or write the path-name for the file in the box to the left of the this button.

How can I ask a question regarding a problem specification?
Press the "Ask" button in the upper right corner. A form will appear where you may write your question and send it to the jury of the contest. Before pressing the "Ask" button you should check whether you are selecting the right problem.
