Counting The Acute Triangles

CodeChefRating 2749Open on judge ↗

A triangle is acute if all its internal angles are acute (o). You are given a set of N points on a 2D plane. Calculate the number of acute triangles that can be formed using points from the set as vertices. Two triangles are different if the set of three vertices of one triangle is not equal to the set of three vertices of the other triangle. Input The first line of the input contains an integ
