面试中遇到的是:给一个正数,包括浮点数,求它的开方,精度为0.01,二分查找的思路。 实现代码: public class Sqrt {public static void main(String[] args) {int num = 2147395599;System.out.println(sqrt(num));}private static int sqrt(int num) {if
要求: Implement int sqrt(int x). Compute and return the square root of x. 注意:使用牛顿梯度法计算平方根,看百度百科或者维基百科 public int mySqrt(int x) {if (x== 0)return 0;double sol = 1;double res = 0;while(sol - re
