## Discussion of Problem 1030. Titanic

What is test #3? I always get WA#3...
Posted by Fokysnik 5 Aug 2006 20:55
Maybe the problem is in acuracy...
but I use pi=2.0*acosl(0.0)...
Maybe it's printing DANGER!
but I use
if (result<99.995) printf("DANGER!\n");
Any ideas?

I always use extended if real type is needed... Maybe test #3 is some special case?

Distance is about 100 miles. Possibly, you make checking something like "distance < 100 then print "Dangerous!!!'".
Instead, you should check not equality of number (dist < 100), but convert it into string, and then check that length(s) < 6 (it equals to condition s < '100.00')

try
const double PI=acos(-1.0);
and you will get AC
