在焦作站的acm网络赛中遇到了一个高精度开根的水题--但是那时候WA了 后面学写java补题还T了orz 所以写一篇文章来记录一下java的大整数类型的基础和开根还有一点心得体会吧 首先给那一题的题面和模板 Jessie and Justin want to participate in e-sports. E-sports contain many games, but they don't know which one to choose, so they use a way to make
Problem DescriptionAs we know, Rikka is poor at math. Yuta is worrying about this situation, so he gives Rikka some math tasks to practice. There is one of them: Yuta has an array A with n numbers. Then he makes m operations on it. There are three ty
python是坠吼的! 原题: 不贴原题,就是高精度开根,结果向下取整 首先二分答案,高精度嘛……python即可 二分右端点设为n会T掉,需要先倍增一个r,while(r **m <= n) r *= 2 然后T掉了,代码如下,亮点自寻 m, n = input(), input() l, r = , n while r ** m < n: r *= < r): md = (l + r) >> if(md ** m <= n): l = md else: r = m
