10元买5瓶酒，2个盖子换一瓶，4个瓶子换一瓶，最多换多少个。
下面贴代码
function compute(yuan){
var num = yuan/2; var jiu = num; var gai = num ; var ping = num ;var total = num;
console.log(num,total)
recompute();
function recompute(){
if(ping>=4 || gai>=2){
total = total+parseInt(gai/2)+parseInt(ping/4);
jiu = parseInt(gai/2)+parseInt(ping/4);
gai = parseInt(gai%2) + jiu;
ping = parseInt(ping%4) + jiu;
console.log(total,jiu,gai,ping);
recompute();
}else{
return false
}
}
return total;
}
compute(10);
