## Description
<section id="description">设计一个收银抽屉功能<code>checkCashRegister()</code> ，它接受购买价格作为第一个参数（ <code>price</code> ），支付作为第二个参数（ <code>cash</code> ），以及现金抽屉（ <code>cid</code> ）作为第三个参数。 <code>cid</code>是列出可用货币的2D数组。 <code>checkCashRegister()</code>函数应始终返回带有<code>status</code>键和<code>change</code>键的对象。返回<code>{status: &quot;INSUFFICIENT_FUNDS&quot;, change: []}</code>如果出现的现金少于到期的更改，或者如果您无法返回确切的更改。返回<code>{status: &quot;CLOSED&quot;, change: [...]}</code>使用cash-in-drawer作为密钥<code>change</code>的值，如果它等于更改到期。否则，返回<code>{status: &quot;OPEN&quot;, change: [...]}</code> ，以硬币和账单中的更改到期，按从最高到最低的顺序排序，作为<code>change</code>密钥的值。如果卡住，请记得使用<a href="http://forum.freecodecamp.org/t/how-to-get-help-when-you-are-stuck/19514" target="_blank">Read-Search-Ask</a> 。尝试配对程序。编写自己的代码。 <table class="table table-striped"><tbody><tr><th>货币单位</th><th>量</th></tr><tr><td>一分钱</td><td> 0.01美元（PENNY） </td></tr><tr><td>镍</td><td> 0.05美元（NICKEL） </td></tr><tr><td>十分钱</td><td> 0.1美元（DIME） </td></tr><tr><td> 25美分硬币</td><td> 0.25美元（季） </td></tr><tr><td>美元</td><td> 1美元（美元） </td></tr><tr><td>五美元</td><td> 5美元（五） </td></tr><tr><td>十美元</td><td> 10美元（10日） </td></tr><tr><td>二十美元</td><td> 20美元（二十美元） </td></tr><tr><td>一百元</td><td> 100美元（一百） </td></tr></tbody></table></section>
