Ulm的judges这样说的

A common mistake is not to handle the two special cases appropriately: Alice and Bob's home may be at the same location and there can occur locations with unknown coordinates. Another possible error is to take as the geometric place of equidistant points the arithmetic mean of the two home locations (which is one point of the geometric place only).

          • 其实我十分不理解用float的动机，精度不足是一方面，它比double还快不了（这个是fpu的pc决定的） (57) frkstyc 2005-04-25 14:23:07
