解题思路:

注意事项:

参考代码:

import java.util.*;

public class z1145 {

public static void main(String args[]) {

Scanner sc = new Scanner(System.in);

int n = sc.nextInt();

double t = 1;

double sum = 0;

for (double i = 1; i <= n; i++) {

if (i == 1)

sum = 100;

else {

sum = sum + 100 / t;

t = 2 * t;

}

}

System.out.printf("%.4f", sum);

}

}
