这道题目还是简单的,但是自己WA了好几次,总结下: 1.对输入的总结,加上上次ZOJ Problem Set - 1334 Basically Speaking ac代码及总结这道题目的总结 题目要求输入的格式: START X Y Z END 这算做一个data set,这样反复,直到遇到ENDINPUT.我们可以先吸纳一个字符串判断其是否为ENDINPUT,若不是进入,获得XYZ后,吸纳END,再进行输出结果 2.注意题目是一个圆周,所以始终用锐角进行计算,即z=360-z; 3.知识点的误…

这道题目说白了是一道平面几何的数学问题,重在理解题目的意思: 题目说,弗雷德想买地盖房养老,但是土地每年会被密西西比河淹掉一部分,而且经调查是以半圆形的方式淹没的,每年淹没50平方英里,以初始水岸线为x轴,平分半圆为y轴,建立如下图的坐标系 问题:给出坐标点(y>0),让你判断在那一年这个坐标点会被淹没. 解决方案:我们可以转换成的数学模型是来比较坐标点到原点的距离与半圆半径的大小即可知道该点是否被淹没,公式如下: 1.由于每年半圆面积增长50平方英里,可得半径递推公式R2=sqrt(100/p…

今天在ZOJ上做了道很简单的题目是关于加密解密问题的,此题的关键点就在于求余的逆运算: 比如假设都是正整数 A=(B-C)%D 则 B - C = D*n + A 其中 A < D 移项 B = A+C + D*n 当B<D时,两边对D取摸,  B = B%D = ( A+C + D*n )%D = (A+C)%D 由此可得此题答案,见代码 #include <cstdio> #include <cstring> int main() { ]; ],ctext[]; w…
