HDU2050 折线分割平面 题目链接 Problem Description 我们看到过很多直线分割平面的题目,今天的这个题目稍微有些变化,我们要求的是n条折线分割平面的最大数目.比如,一条折线可以将平面分成两部分,两条折线最多可以将平面分成7部分,具体如下所示. Input 输入数据的第一行是一个整数C,表示测试实例的个数,然后是C 行数据,每行包含一个整数n(0<n<=10000),表示折线的数量. Output 对于每个测试实例,请输出平面的最大分割数,每个实例的输出占一行. Samp…

题目地址: http://poj.org/problem?id=1314 题意: 给出一串的点,有些点可以构成正方形,请按照字符排序输出. 因为这道题的用处很大, 最近接触的cv 中的Rectangle Detection 中就有方法使用到了这个算法. 但实际中使用的算法还是暴力. 不过因为数据点较少,可以直接快排之后,再来个迭代,就得到答案了 #include <cstdio> #include <iostream> #include <cstring> #inclu…

Given n points on the XY plane, count how many regular rectangles are formed. A rectangle is regular if and only if its sides are all parallel to the axis.InputThe first line contains the number of tests t (1 ≤ t ≤ 10). Each case contains a single lin…

Counting rectangles By counting carefully it can be seen that a rectangular grid measuring 3 by 2 contains eighteen rectangles: Although there exists no rectangular grid that contains exactly two million rectangles, find the area of the grid with the…
