( 3046 ) B Number of Triplets PROGRAMMING binary search brute force 1300

B'You are given n points on a plane. All points are different. Find the number of different groups of three points (A, xe2 x80 x89B, xe2 x80 x89C) such that point B is the middle of segment AC. The groups of three points are considered unordered, that is, if point B is the middle of segment AC, then groups (A, xe2 x80 x89B, xe2 x80 x89C) and (C, xe2 x80 x89B, xe2 x80 x89A) are considered the same. The first line contains a single integer n (3 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x893000) -- the number of points. Next n lines contain the points. The i-th line contains coordinates of the i-th point: two space-separated integers xi, xe2 x80 x89yi ( xe2 x80 x89- xe2 x80 x891000 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89xi, xe2 x80 x89yi xe2 x80 x89 xe2 x89 xa4 xe2 x80 x891000). It is guaranteed that all given points are different. Print the single number -- the answer to the problem. '...
