题目:http://acm.fzu.edu.cn/problem.php?pid=2140 题意: 题目大意:给出n,要求找出n个点,满足: 1)任意两点间的距离不超过1: 2)每个点与(0,0)点的距离不超过1: 3)有n对点之间的距离刚好为1: 4)n个点组成的多边形面积大于0.5: 5)n个点组成的多边形面积小于0.75: 思路:只要有4个点以上就是,构造时先找出四个点,再在半径为1的圆上找点就行. 很巧妙的一道题目呀.... #include <iostream> #include &…

在线springmvc_rest demo 由于下一版本的rapid-framwork需要集成spring RESTful URL,所以研究了一下怎么搭建. 并碰到了一下问题. springmvc 3.0 中增加 RESTful URL功能,构造出类似javaeye现在的URL. rest介绍 , 这里还有struts2 rest构造的一篇文章: 使用 Struts 2 开发 RESTful 服务 简单例子如下,比如如下URL /blog/1  HTTP GET =>    得到id = 1的b…
题目链接:fzu 2035 Axial symmetry 题目大意:给出n个点,表示n边形的n个顶点,判断该n边形是否为轴对称图形.(给出点按照图形的顺时针或逆时针给出. 解题思路:将相邻两个点的中点有序的加入点集,即保证点是按照图形的顺时针或逆时针出现的,然后枚举i和i + n两点的直线作为对称轴.判断其他所有点是否对称即可. #include <stdio.h> #include <string.h> #include <stdlib.h> #include <…
