关于ACM错误提示的说明

 

下面是一般JudgeOnline系统所有可能产生的结果,如果对返回的结果不明,看看解释吧

Waiting: Your program is being judged or waiting to be judged.

 

Accepted (AC): Congratulations! Your program has produced the correct output!

 

Presentation Error (PE): Your program's output format is not exactly the same as required by the problem, although the output is correct. This usually means the existence of omitted or extra blank characters (white spaces, tab characters and/or new line characters) between any two non-blank characters, and/or blank lines (a line consisting of only blank characters) between any two non-blank lines. Trailing blank characters at the end of each line and trailing blank lines at the of output are not considered format errors. Check the output for spaces, blank lines, etc. against the problem's output specification.

 

Wrong Answer (WA): Your program does not produce the correct output. Special judge programs will possibly return Wrong Answer in place of Presentation Error for simplicity and robustness.

 

Runtime Error (RE): Your program has failed during the execution. Possible causes include illegal file access, stack overflow, out of range in pointer reference, floating point exception, division by zero and many others. Programs that stay not responding for a long time (not consuming CPU cycles) may also be considered to have encountered runtime errors.

 

Time Limit Exceed (TLE): The total time your program has run for has exceeded the limit.

Each problem has two time limits - TOTAL TIME LIMIT and CASE TIME LIMIT. The former is the total time allowed for your program to deal with all input files. And the latter is the total time allowed for your program to deal with a single input file. Exceeding either one will lead to Time Limit Exceed. If you get Time Limit Exceed but find that your program has run for less time than is limited, your program must have exceeded that CASE TIME LIMIT.

Problems without a special demand on the time limit for a single input file will have its case time limit is trivially set as the same as its total time limit and the phrase "Case Time Limit" will not show up under the problem title.

 

Memory Limit Exceed (MLE): The maximum amount of memory that your program has used has exceeded the limit.

 

Output Limit Exceed (OLE): Your program has produced too much output. Currently the limit is twice the size of the file containing the expected output. The most common cause of this result is that your programs falls into an infinite loop containing some output operations.

 

Compile Error (CE): The compiler fails to compile your program. Warning messages are not considered errors. Click on the judge's reply to see the warning and error messages produced by the compiler.

 

No such problem: Either you have submitted with a non-existent problem id or the problem is currently unavailable (probably reserved for upcoming contests).

 

System Error: The judge cannot run your program. One example is that your program requires much more memory than hardware limitation.

 

Validate Error: The special judge program fails in checking your output, which means it may contain some bugs. If you get this result, please contact the administrator. (Of course, this also means your output is probably wrong).
