Quadrilaterals

CodeChefOpen on judge ↗

You are given the coordinates of the vertices of a square in the 2-d plane. All vertex coordinates will be integers. Now consider all convex quadrilaterals which also have integer coordinates for their vertices such that the midpoints of their edges are the vertices of the original square. Find the sum of areas of all such quadrilaterals. Input The first line of input gives T, the number of t
