题目链接：uva 10574 - Counting Rectangles
题目大意：给出n个点，问选出4个点作为定点，可以组成多少个平行与坐标轴的矩形。
解题思路：首先将点按照x排序(优化)，然后处理出所有平行于y轴的线段，记录这些线段的y1和y2，接着只要找出y1和y2值均相等的边，C(2cnt).

10574 - Counting Rectangles
题目链接
题意：给定一些点，求能够成几个矩形
思路：先把点按x排序，再按y排序，然后用O(n^2)的方法找出每条垂直x轴的边，保存这些边两点的y坐标y1, y2。之后把这些边按y1排序，再按y2排序，用O(n)的方法找出有几个连续的y1, y2都相等，那么这些边两两是能构成矩形的，为C2cnt种，然后累加起来就是答案
