Sphere Online Judge (SPOJ) - Problem CIRU [求圆并的若干种算法,圆并扩展算法]_AekdyCoin的空间_百度空间 参考AekdyCoin的圆并算法解释,根据理解写出的代码.圆并这么多题中,最基础一题. 操作如下: (1)对一个圆,获得所有与其他圆的交点作为时间戳. a.如果这个圆不被其他任何圆覆盖,这个圆直接保留. b.如果Case中有两个完全重合的圆,可以保留标号小(或大)的圆,也只保留这一个. (2)每经过一个时间戳就对计数器加减,如果计数器从0变…

[SPOJ-CIRU]The area of the union of circles/[BZOJ2178]圆的面积并 题目大意: 求\(n(n\le1000)\)个圆的面积并. 思路: 对于一个\(x\),我们可以用线段覆盖的方法求出被圆覆盖的长度.用\(f(x)\)表示横坐标为\(x\)时覆盖的长度,则我们可以对\(f(x)\)积分来得到答案.注意面积不连续的部分要分开求. 源代码: #include<cmath> #include<cstdio> #include<cc…

[题目分析] 圆的面积并. 直接Simpson积分,(但是有计算几何的解法,留着flag). simpson积分,如果圆出现了不连续的情况,是很容易出事情的.(脑补一下) 但是没有什么办法,本来就是一种取巧的做法,还能指望这暴力积分做什么. [代码] #include <cstdio> #include <cstring> #include <cmath> #include <cstdlib> #include <map> #include &l…
