发现OJ题目中很多题目都PE，原来是最后一行的\n的问题。
记得原来的HUSTOJ 
CORE是有几条语句处理这个的，即忽略最后有没有\n。
所以建议在所用的ZOJ的那部分评测代码后面也加上这样的机��
�。
毕竟因为最后一个换行总让人PE很不爽...

try r504 to see if it got your point

Original comment by newsc...@gmail.com on 10 Nov 2010 at 1:02

[GoogleCodeExporter]

I tried, it doesn't work, remained PE.
But when I switched to the original HUSTOJ core, everything became okay. 
I think you still have to fix this in ZOJ core (compare function), in another 
way...

can you upload a sample of this issue in FPS format

[GoogleCodeExporter]

try r508 ?

Original comment by newsc...@gmail.com on 10 Nov 2010 at 2:38

• Changed state: Accepted

[GoogleCodeExporter]

r508 still didn't work, it can't forgive the last '\n' either.

is there any miss understanding?
check my source
http://acm.sie.edu.cn/JudgeOnline/showsource.php?id=940

i've added
   printf("\n\n\n");
 before return 0;

it AC.

Original comment by newsc...@gmail.com on 11 Nov 2010 at 9:02

[GoogleCodeExporter]

Yes, you ACed because I switched to the original HUSTOJ comparition function...

When I use the ZOJ compare(), many problems PE...

Original comment by cn-...@china.com.cn on 11 Nov 2010 at 9:03

[GoogleCodeExporter]

i'm using the same data and r508 with ZOJ-compare.
i AC too.

[GoogleCodeExporter]

have you did what i recommanded in issue27 ?

Original comment by newsc...@gmail.com on 11 Nov 2010 at 9:06

[GoogleCodeExporter]

i mean

{{{
cd /home/judge/data
find . -name *.in -exec fromdos -d {} \;
find . -name *.out -exec fromdos -d {} \;
}}}

Original comment by newsc...@gmail.com on 11 Nov 2010 at 9:07

[GoogleCodeExporter]

No '\r\n' in those files...

Original comment by cn-...@china.com.cn on 11 Nov 2010 at 9:18

[GoogleCodeExporter]

I saw there's a function 
{{{
void delnextline(char s[]) {
    int L;
    L = strlen(s);
    while (L > 0 && (s[L - 1] == '\n' || s[L - 1] == '\r'))
        s[--L] = 0;
}
}}}
in the original HUST judge_client which can ignore all the \r or \n characters.

i dump your file into this demo,it works nice.

[GoogleCodeExporter]

But all in all, I think since 

#define STD_MB 1048576 //10M Byte, I think
#define STD_F_LIM (STD_MB<<5)

so the limit output file size in HUSTOJ judge_client can reach 32MB, it's 
enough for any type of contests.

the r504 is ignore all space character

[GoogleCodeExporter]

the memory alloc and free operation slow down the judger and there is some data 
bigger than 32m in my system

Original comment by newsc...@gmail.com on 11 Nov 2010 at 9:38

[GoogleCodeExporter]

But I tested, even the ZOJ_compare you modified could not ignore the '\n' 
characters (at least the last one), while the original HUSTOJ_compare can.

Original comment by cn-...@china.com.cn on 11 Nov 2010 at 9:39

[GoogleCodeExporter]

just try to make a PE for this 
http://www.newsclan.com/JudgeOnline/problem.php?id=1104
then i could find out what's really wrong.

Original comment by newsc...@gmail.com on 11 Nov 2010 at 9:40

[GoogleCodeExporter]

maybe you can upload your data file themselves here,not just FPS.
FPS export function can fix \r\n problem.

Those are test data files of this problem in our OJ
