The moving sand dunes of the desert render the excavations difficult and thus once three vertices of a polygon are discovered there is a need to cover the entire polygon with protective fabric. 输入Input contains multiple cases. Each case describes one polygon. It starts with an integer n ≤ 50, the number of vertices in the polygon, followed by three pairs of real numbers giving the x and y coordinates of three vertices of the polygon. The numbers are separated by whitespace. The input ends with a n equal 0, this case should not be processed. 输出Description The Archeologists of the Current Millenium (ACM) now and then discover ancient artifacts located at vertices of regular polygons.
