Determine a circle based on three points.
Calculate the radius and the coordinates of the center.
For the general form of the equation of a circle, let the equation be
x^2 + y^2 + lx + my + n = 0.
There are three sets of data to be entered.
If the data consists of coordinate points, a circle containing those three points will be determined.
Please enter distinct coordinate points (duplicates will not be included in the output).
If l, m, and n can be determined, the results will be output (only when the values are finite).
