There are n points on the plane. You can move a point from a coordinate \((x_1, y_1) \) to the coordinate \((x_2, y_2)\) за стоимость, равную  \(\sqrt{(x_1 - x_2)^2 + (y_1 - y_2) ^ 2}\)

Your task is to minimize the total cost of moving all points in such a way that they lie on the same straight line. Note that you can move the points in any way you like.
 

The first line contains an integer \(n\) — number of points \((2 <= n <= 10^3)\). Next in \(n\)  the lines list the coordinates of these points\(x_i\)and \(y_i\) — integers, modulo not exceeding  \(10^6\)

Print the minimum total distance to which the points should be dragged, with an absolute or relative error of no more than \(10^{-6}\)
