介绍

您是一家大型零售商店中电子部门的经理，一年中最大的销售日是本星期五。为了帮助管理人群，您的商店正在实施最大交易的票务系统，客户必须在购买商品之前出示票证。您的工作是编写一个程序来验证票证。

由于商店中唯一可用的计算机（由于预算削减）是一台损坏了键盘的恐龙（而且您所拥有的都是USB键盘，这些键盘不兼容），因此您必须用鼠标输入程序。因此，您的程序应尽可能短。

产品展示

您的商店正在使用以下五种不同的产品进行销售。每个产品都有一个全小写的名称，以及在一天中的什么时候可以购买多少个不同的规则。

• television：有5库存的平板电视可能从00:00:00（午夜）到采购00:59:59。
• smartphone：有10智能手机库存，但从00:00:00（午夜）起排队的所有客户在00:59:59用完时会收到一张代金券。
• tablet：有些10平板电脑可以随时购买。
• laptop：从00:00:00（午夜）到可以购买数量不限的笔记本电脑07:59:59。
• lightbulb：随时可以购买无限数量的灯泡。

输入值

多行字符串，每行采用以下格式。行按时间戳排序。

<time stamp> <product name> <ticket number>

• 票证号码为8位数字。最后一位数字是一个校验位，等于前七个数字模10的总和。要生效，票证号必须具有正确的校验码，并且必须严格大于所有先前的票证号。
• 产品名称是上面列出的字符串之一。
• 时间戳是一天中的格式的时间HH:MM:SS，其中HH是从00-23两位数小时，MM并且SS是两位数分钟和秒分别。

输出量

输出是以下字符串之一，每张票证一行。必须按顺序应用条件。

1. Expired offer （适用于电视，智能手机和笔记本电脑。）门票的时间戳是在购买产品的截止日期之后。
2. Invalid ticket 票证号小于或等于前一张票证的号，或者校验位无效。
3. Give voucher （适用于智能手机。）该产品缺货，但是在报价过期之前排队的所有客户都可以进行雨淋检查。
4. Out of stock（适用于电视和平板电脑。）所有产品均已售出。抱歉，数量有限。
5. Accepted满足所有条件，所以给他们产品。请注意，只有接受的票证才能减少库存的物品数量。

我试图使该示例涵盖所有可能的输出方案，但是如果不清楚，请发表评论。

这是代码高尔夫球，您可以编写程序或函数，并且不允许使用标准漏洞。

使用Javascript（ES6），396个 433 419字节

h=0;f=1/0;i={television:{c:5,s:0,e:1},smartphone:{c:10,s:0,e:1,v:1},tablet:{c:10,s:0,e:24},laptop:{c:f,s:0,e:8},lightbulb:{c:f,s:0,e:24}};while(1){t=prompt().split(' ');a=t[0];r=a[0]+a[1]-0;o=i[t[1]];m=0;z='Accepted';u=t[2]-0;u<=h||(u-u%10+'').split('').reduce((p,c)=>-(-p-c))%10!=u%10?m='Invalid ticket':0;r<o.s||r>=o.e?m='Expired offer':0;if(!m)o.c?o.c--:(o.v?z='Give voucher':m='Out of stock');!m?h=u:0;alert(m?m:z)}

编辑：通过使用es6大箭头功能减小大小

更具可读性：

h=0
f=1/0
i={television:{c:5,s:0,e:1},smartphone:{c:10,s:0,e:1,v:1},tablet:{c:10,s:0,e:24},laptop:{c:f,s:0,e:8},lightbulb:{c:f,s:0,e:24}}
while(1){t=prompt().split(' ')
a=t[0]
r=a[0]+a[1]-0
o=i[t[1]]
m=0
z='Accepted'
u=t[2]
if(u<=h||(u-u%10+'').split('').reduce(function(p,c){return-(-p-c)})%10!=u%10)m='Invalid ticket'
if(r<o.s||r>=o.e)m='Expired offer'
if(!m){if(o.c)o.c--
else o.v?z='Give voucher':m='Out of stock'}if(!m)h=u
alert(m?m:z)}

有趣的是，较长的代码更快：http : //jsperf.com/compare-read

具有相同逻辑的GUI：

var app = angular.module('app', []);

app.controller('MainCtrl', function MainCtrl ($scope) {
  $scope.items = {

    lightbulb: {c: Infinity, s: 0, e: 24},
  };
  
  var h = -1;//highest
  
  $scope.hours_offset = 0;

  }
  
  $scope.purchase = function() {
    if ($scope.selected_item === -1)
      return;

    var ticnum = '';
    var msg = 'Accepted';
    
    for(var key in $scope.ticket)
      ticnum+=$scope.ticket[key];
    
    var d = new Date();
    
    //Variable declarations to setup for code like the code I designed for console
    r = d.getHours()-$scope.hours_offset;//hour
    o = $scope.items[$scope.selected_item];//item
    m = 0//msg
    z = 'Accepted'//default_msg
    u=ticnum
    
    //This is copied from my console code
    if(ticnum<=h||(ticnum-ticnum%10+'').split('').reduce(function(p,c){return-(-p-c)})%10!=ticnum%10)m='Invalid ticket'
	if(r<o.s||r>=o.e)m='Expired offer'
	if(!m){if(o.c)o.c--
	else o.v?z='Give voucher':m='Out of stock'}if(!m)h=ticnum
	
    msg = m?m:z;
    
    $scope.history.unshift({
