题目描述
Farmer John is thinking of selling some of his land to earn a bit of extra
income. His property contains n trees (3≤N≤300), each described
by a point in the 2D plane, no three of which are collinear. FJ is thinking
about selling triangular lots of land defined by having trees at their
vertices; there are of course L=(3N) such lots he can consider,
based on all possible triples of trees on his property.
A triangular lot has value v if it contains exactly v trees in its
interior (the trees on the corners do not count, and note that there are no
trees on the boundaries since no three trees are collinear). For every v=0…N−3, please help FJ determine how many of his L potential lots have
value v.
输入格式
The first line of input contains N.
The following N lines contain the x and y coordinates of a single tree;
these are both integers in the range 0…1,000,000.
输出格式
Output N−2 lines, where output line i contains a count of the number of
lots having value i−1.
