-= zju online judge =

faq: http://acm.zju.edu.cn/faq.php

其中比较重要的是：
{{{
Q:What is the compiler the judge is using and what are the compiler options?
A:The online judge system is running on Redhat Linux. We are using GNU GCC/G++ for C/C++ compile and GPC/Free Pascal for pascal compile.
}}}

{{{
Q:What is the meaning of the judge's reply XXXXX?
A:Here is a list of the judge's replies and their meaning:

Queuing : The judge is so busy that it can't judge your submit at the moment, usualy you just need to wait a minute and your submit will be judged.

Accepted : OK! Your program is correct!.

Presentation Error : Your output format is not exactly the same as the judge's output, although your answer to the problem is correct. Check your output for spaces, blank lines,etc against the problem output specification.

Wrong Answer : Correct solution not reached for the inputs. The inputs and outputs that we use to test the programs are not public (it is recomendable to get accustomed to a true contest dynamic ;-).

Runtime Error : Your program failed during the execution (segmentation fault, floating point exception...). The exact cause is reported to the user.

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. This usually occurs if it goes into a infinite loop. Currently the output limit is 1M bytes.

Compile Error : The compiler (gcc/g++/gpc) could not compile your ANSI program. Of course, warning messages are not error messages. Click the link at the judge reply to see the actual error message.

Out Of Contest Time: this message can only appear during a contest, if a program is submitted out of contest time.

No such problem: Either you have submitted a wrong problem id or the problem is unavailable.

Restricted Function: Your program tried to call restricted functions. For example, maybe you have tried to open a file which is forbidden on ZOJ.

Q:Why did I get a Compile Error? It's well done!
A:There are some differences between GNU and MS-VC++, such as:
    * main must be declared as int, void main will end up with a Compile Error.
    * i is out of definition after block "for(int i=0...){...}"
    * itoa is not an ANSI function.
    * __int64 of VC is not ANSI, but you can use long long for 64-bit integer.

Q:What does SIGSEGV in Runtime Error stand for?
A:The following messages will not be shown to you in contest. Here we just provide some tips:
SIGSEGV --- Segment Fault. The possible cases of your encountering this error are:

    * 1.buffer overflow --- usually caused by a pointer reference out of range.
    * 2.stack overflow --- please keep in mind that the default stack size is 8192K.
    * 3.illegal file access --- file operations are forbidden on our judge system.

SIGFPE  --- Divided by 0
SIGBUS  --- Hardware Error. //please contact us
SIGABRT --- Programme aborted before it should be finished.
man 7 signal under Linux for more information
}}}

{{{
Q:Where is the input and the output?
A:Your program shall read input from stdin('Standard Input') and write output to stdout('Standard Output').For example,you can use 'scanf' in C or 'cin' in C++ to read from stdin,and use 'printf' in C or 'cout' in C++ to write to stdout.
User programs are not allowed to open and read from/write to files, you will get a "Runtime Error" if you try to do so.
Here is a sample solution for problem 1001 using C++:

#include <iostream>
using namespace std;

int main()
{
    int a,b;
    while(cin >> a >> b)
        cout << a+b << endl;
}

Here is a sample solution for problem 1001 using C:

#include <stdio.h>

int main()
{
    int a,b;
    while(scanf("%d %d",&a, &b) != EOF)
        printf("%d\n",a+b);
}

Here is a sample solution for problem 1001 using PASCAL(both GPC&FPC):


program p1001(Input,Output); 
var 
  a,b:Integer; 
begin 
   while not eof(Input) do 
     begin 
       Readln(a,b); 
       Writeln(a+b); 
     end; 
end.

下面给大家搜集一些大学生程序设计竞赛的题目，给大家练习使用。在练习之前，有几点需要注意：
 1. 很多题目都是英文的，这是和国际ACM大学生程序设计竞赛接轨的。所以首先要学会看懂题目。
 1. 很多题目都有在线判题系统（Online Judge）。将你所做的程序，在对应的判题系统中提交以后，系统会自动给出结果。结果有几类：Accepted(正确)，Compile Error(编译错误)，Runtime Error(运行时错误)，Wrong Answer(答案错误)，Time Limit Exceed(超时)，Memory Limit Exceed(超过内存)等。
 1. 每个题目的输入输出都有严格的要求，如果不符合要求，将会被认为是错误（Wrong Answer）的。
 1. 每个题目都有严格的时间和空间要求。在线判题系统会用很多苛刻的输入来测试程序，你的程序要在所有测试数据中都能够按时完成才能够获得成功（Accepted）。
 1. 在线判题系统要求提交的程序使用Ansi/ISO标准书写，所以不标准的语法将会得到Compile Error，比如：void main(){}。
