Burning

The sky is BURNING,and you find there are n triangles on a plane.
For every point p,if there's exactly k triangles contains it,then define it's thickness as k.
For every i from 1 to n,calculate the area of all points whose thickness is i.

The first line contains integer T(T <= 5),denote the number of the test cases.
For each test cases,the first line contains integer n(1 <= n <= 50),denote the number of the triangles.
Then n lines follows,each line contains six integers x₁, y₁, x₂, y₂, x₃, y₃, denote there's a triangle with vertices (x₁, y₁), (x₂, y₂), (x₃, y₃).
0 <= x_i, y_i <= 100 for every i.

For each test cases,print n lines,the i-th is the total area for thickness i.
The answer will be considered correct if its absolute error doesn't exceed 10^-4.

Triangle can be degenerated(3 points on a line,even 3 points are the same).
