注意事项:   別忘了重置变量





参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] ahes) {

Scanner sc = new Scanner(System.in);

int bottle = sc.nextInt();

int count = 0; 

int empty ;

do{                    // 大循环

          while (bottle!=0)                 //小循环 

{

count += bottle/3;

empty = bottle % 3;

bottle = empty  + (bottle / 3);

if (bottle == 2) {

count += 1;

break;

}

if (bottle == 1)

break;

}   System.out.println(count);

count=0;empty=0;

bottle  = sc.nextInt();

}while(bottle!=0);

}

}
