题目描述

There areatetrahedrons andbspheres in the 3D-splace, you’re asked to calculate the volume occupied by at least one of them (i.e. volume of the union of the ob jects).


输入
There will be at most 20 test cases. Each case begins with two integersa,b, the number of tetrahedrons and the number of spheres (1<=a,b<=5). The nextalines each contains 12 integers:x1,y1,z1,x2,y2,z2,x3,y3,z3,x4,y4,z4, the coordinates (xi,yi,zi)(1<=i<=4) of the four vertices of a tetrahedron. The nextblines each contains 4 integersx,y,z,r, the coordinates of the center (x,y,z) and the radiusr(r<=3). All the coordinate values are integers with absolute values no more than 5. The input is terminated bya=b=0.
输出
For each test case, print a single line, the volume occupied by at least one of them, rounded to three decimal points.
