long ago i tried to solve this problem and got several WA and now again when i'm trying fresh its all the same.. WA

so i'm posting my code and hope someone will point out a test case that it fails...

Code: Select all


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

const long double pi=3.1415926535897932384626433832795 ;//acos(-1);

int main()
{
	long double r,n,v;
	int k,tc=1;

	while(1)
	{
		scanf("%Lf%Lf",&r,&n);
		if(r+n==0.0) break;

		printf("Case %d:\n",tc++);
		for(k=2;k<=20;k+=2)
		{
			v= pi/2 - ( n+ n/pi/k )/r; 
			printf("%.5Lf\n", v*180/pi );
		}
	}

	return 0;
}

thanks in advance.
