import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
double input = sc.nextDouble();
while(input != 0.00){
double sum = 0;
int i = 0;
while(sum < input){
i++;
sum += (1.0 / (i + 1.0));
}
input = sc.nextDouble();
System.out.println(i + " card(s)");
}
}
}
（二）POJ1004
题目地址：http://poj.org/problem?id=1004
No Problem.
源代码如下：
import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
double sum = 0;
for(int i = 0; i < 12; i++){
sum += sc.nextDouble();
}
System.out.printf("$%.2f\n", sum / 12);
}
}
