贴代码: 题目意思:已知r水的下半径,R水的上半径,H为圆台高度,V为水的体积,求水的高度,如图: 水的高度一定在0-100,所以在这个区间逐步二分,对每次二分出的水的高度,计算相应的体积,看看计算出的这个体积和已知的水体积之差是否小于1e-9,如果小于,就说明计算出的体积已经无限接近真正的水体积,那么这次二分出的水高度即为所求高度,如果大于1e-9,就再次二分,直到二分出正确的高度为止.…
<题目链接> 题目大意: 一个圆台型的杯子,它的上底半径和下底半径已经给出,并且给出它的高度,问你,体积为V的水倒入这个杯子中,高度为多少. 解题分析: 就是简单的二分答案,二分枚举杯中水的高度,然后根据几何计算出该高度下,水的上半径,然后计算出该高度下水的体积,在与实际水的体积进行比较,从而确定最终的答案. #include <cstdio> #include <cstring> #include <cmath> const double PI=acos(…
There are n people and k keys on a straight line. Every person wants to get to the office which is located on the line as well. To do that, he needs to reach some point with a key, take the key and then go to the office. Once a key is taken by somebo…
题意:有两个服务要求被满足,服务S1要求x1数量的资源,S2要求x2数量的资源.有n个服务器来提供资源,第i台能提供a[i]的资源.当你选择一定数量的服务器来为某个服务提供资源后,资源需求会等量地分担给它们,要求每台服务器承担的资源需求不超过其所能提供的资源需求.给定一种合法的方案,每台服务器要么没有被分配给任何一个服务,或者被分配给其中一个服务. 对服务器按能提供的资源从小到大排序.枚举给S1分配的服务器数量i,然后在a数组中二分,就可以得到给S1提供的是哪i台服务器,它们占据了a数组中连续的…
