### OJ 使用手册

##### 各状态含义
• Accepted : Good!Your program is correct!
• Presentation Error : Your program’s output format is not exactly the same as required by the problem, although the output is correct.
• Wrong Answer : Correct solution not reached for the inputs.
• Runtime Error : If you are using Java, please check the class signature as well as the main method signature, and don’t use any class which is not allowed. If you are using other languages, your program may have executed a forbidden operation, like invoking privileged syscalls, file operation, etc. Notice that buffer overflow and stack overflow can also lead to this error.
• Time Limit Exceeded : Your program tried to run during too much time.
• Memory Limit Exceeded : Your program tried to use more memory than the judge default settings.
• Output Limit Exceeded : Your program tried to write too much information.
• Compilation Error : 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.
• System Error: The judge cannot run your program. One example is that your program requires much more memory than hardware limitation.
• Waiting : The judge is so busy that it can’t judge your solution at the moment.
• Compiling : Your solution is being compiled to binary form by the compiler.
• Running : Your program is running on the server and fed with input data if necessary.
