使用Java自己实现开根号运算,网上也有不少代码,多数都使用String或者数组.这里写一段只使用double基础数据类型实现的方法. private static double sqrt(int n, int p) { double lower = 0; while (lower * lower < n) { lower++; } --lower; int flag = 1; int d = 10; while (flag <= p + 1) { d = 10; for (int x = 1

因为开根号能使数字减小得非常快 所以开不了几次(6次?)很大的数就会变成1..... 所以我们可以维护区间最大值,若最大值>1,则继续递归子树,暴力修改叶节点,否则直接return (好像也可以维护区间被开方的次数,但我不会...QAQ) #include<cstdio> #include<iostream> #include<cmath> #define int long long #define R register int #define ls (tr<
