标题:切面条

  • 一根高筋拉面,中间切一可以得到2根面条。
  • 如果先对折1次,中间切一刀,可以得到3根面条。
  • 如果连续对折2次,中间切一刀,可以得到5根面条。
  • 那么,连续对折10次,中间切一刀,会得到多少面条呢?
  • 答案是个整数,请通过浏览器提交答案。不要填写任何多余的内容。
public class Test01_切面条 {       public static void main(String[] args) {           //TODO: 面条根数始终和切点数差 1        //     折数   切点数   面条根数        //      0       1 2^0    2        //      1       2 2^1    3        //      2       4 2^2    5        //      3       8 2^3    9        int count = (int) (Math.pow(2,10)+1);        System.out.println(count);  // 1025     }}
