Amazing!!! I have passed all the test case in 10011.in, but I still get WA!!!

help!! I believe my algorithm have no problem, precision error??



#include <stdio.h>
#include <math.h>

const double Pi = 3.1415926535897932384626;
const double EPS = 1E-8;

struct Tpoint
{
double x, y;
};

const ...

For this testdata , my Accepted program output nothing .. not "Impossible."

And my method is the same as hujialie's , it's the correct algorithm for this problem. Maybe he made some mistake on programming.

I know the reason now!

there are many blank lines at the end of the test data . so if we use EOF , it can't works well ...... this is my code...

{$S-,R-}

program UVA10382;

const
maxn = 10000;

type
tseg = record
l , r : double;
end;

var
seg : array [ 1 .. maxn ] of tseg;
w , l : double ...

I got WA too....

Is there any trick in the test data ? I need some data.

help!
