There's no code here.

The output shouldn't start with a blank line.

#include <stdio.h>
#include <math.h>
int main(int argc, const char * argv[])
{

long long int test,d,v,u,i;
scanf("%lld",&test);
for (i=1; i<=test; i++) {
scanf("%lld %lld %lld",&d,&v,&u);
if (u<=v||u==0) {
printf("Case %lld: can't determine\n",i);
continue;
}
printf("Case %lld: %.3lf\n",i,(1.*d/sqrt(u*u-v*v)-d*1./u));
}
return 0;
}

here is my code. It seems everything all right to me.. But wrong answer.. So please help me to find the bug///

what if v is 0?

If someone could please take a look at this code. It's sick, I've read all your previous hints and still getting WA on it.

Use code tags. My advice to you -> always copy/paste output format from sample or problem description.

Sample Output Your Output Don't forget to remove your code after getting accepted.

There is just no way I made such mistake! Thank you very much.
