adding two new lines at the end of all output gave me AC as well, while only putting one new line didnt

I have not found any reason of getting PE
Can anyone find it out for me?
Thank You

1. Read this

2. Search before post.

3. Don't open new thread if related thread exists.

Hi,

The judge and I dont seem to be getting along very well

Guys please see if you can help me. Here is my program...

Code: Select all

	}
}

int main()

	return 0;
}
#endif

I cant help but think the judge is being anal and giving a WA instead of a PE.

There should be a blank line after every case.

Posted: **Mon May 05, 2008 9:17 am**

Hi Jan,

I think I have put a blank line in between each output as asked for in the problem. Here is the sample output for the input given in the problem...

(see http://bp3.blogger.com/_VTIyYPvHp_0/SB6 ... -h/LCD.JPG )

Note: The "Press any key to continue" text is not part of the output.

Posted: **Mon May 05, 2008 9:39 am**

There should be a blank line before 'Press any key to continue'. Read the description again, I have already mentioned it.

no body here??
help please...

i still can't get AC..
the judge keep give me PE..

Posted: **Mon Jun 16, 2008 6:55 pm**

thx for all this instructions , I did all wat u said and I compared my output with an accepted code , using fstream and I highlighted them , they where typical not even a change in white space ,, and the accepted code don process a leading zero , which mean it is not tested by Judge , ok now wat is the problem here in that semi perfect code ??? plz fast answer , am losing my nerves and Iam gonna Suicide !!!

and thx for advance who will matter my reply

Hello! Please tell me why I got TLE????
It doesn't work only when n>=100 000 000(more than 8 digits). But it isn't in task.

I just don't know why I got RE in this question

I consider blank lines on input, s and n out of the specification limit. I also tried a great test case, and it works

can someone help me? I'm desperate

here's my code:

Perhaps someone would be willing to help me figure out why I'm receiving a Presentation Error on this problem? As far as I can tell, the output is correct and matches the test cases available. Specifically, I've checked:

No extra blanks at the end of lines
All digits are padded with necessary spaces to fill out the full width
Newline after each case (adding a second newline after the last case as some have suggested still results in a PE)
Leading zeros are displayed (stripping leads at a WA result)

Are there any other special cases I may not be seeing? Thanks in advance for your help.
