I only correct my formula to simply one and get AC.

Code: Select all

#define delta(x,y) 2*sqrt(rad[x]*rad[y])

Why with prev I got WA?????

Zaspire

I read all post before, and i pass all test. But WA. WHY? Help please!

Code: Select all

/* CUT*/

#define delta(x,y) sqrt((rad[x]+rad[y])*(rad[x]+rad[y])-abs(rad[x]-rad[y])*abs(rad[x]-rad[y]))

/*CUT*/

I corect my program and it's work with 1/.5 but still get WA.
After that I simple remove line

Code: Select all

if (abs(res)<0.0001) printf("0.000\n");

if abs(res)<0.0001 the output must be 0.000, But it's wrong?

May be you need some correct in you code:
int x1,y1,x2,y2,x3,y3,x4,y4
if(fabs((c1/b1)-(c2/b2))<0.001)
