:cry: :cry: :cry: :cry: :cry: :cry: :cry: :cry: :cry:

# define PI (2*acos(0))

struct Tpoint
{ long x; long y ...

WA again.
and my programme pass all test you give me.

I puzzled.
if there are three point p p[i+1] p[i+2] in one line,

Sorry,but I got the exactly correct answer about the case,

Have you any other case?

I don't know why I got WA
can Anyone give me the input/output file?

# include <stdio.h>
# include <math.h>
# define MaxN 200
# define PI 3.14159265359

struct Tpoint
{ long x; long y;}
Polygon[MaxN];

typedef struct Tpoint line;
typedef struct Tpoint point;

int N;
int Clockwise;
