酒瓶和啤酒的问题

Posted 2023-02-27 劲火星空

一、题目

每瓶啤酒2元，2个空酒瓶或4个瓶盖可换1瓶啤酒。10元最多可喝多少瓶啤酒？

二、程序

package test;
public class Solution 
	public static int all = 5;	
	public static int leftBottle;	
	public static int leftTop;	
	public static void main(String[] args) 		
		all = all + drink(5,5);		
		System.out.println("总共能喝"+all);		
		System.out.println("剩下酒瓶个数"+leftBottle);		
		System.out.println("剩下盖子个数"+leftTop);	
		
	public static int drink(int bottle, int top) 		
		if(bottle >=2 || top >=4)			
			leftBottle = (bottle/2)+(bottle%2)+(top/4);			
			leftTop = (top/4) + (top%4) + (bottle/2);			
			return  (bottle/2) + (top/4) + drink(leftBottle,leftTop);		
				
		return 0; 	
	

执行结果如下

总共能喝15
剩下酒瓶个数1
剩下盖子个数3
