Description
checkCashRegister() ，它接受购买价格作为第一个参数（ price ），支付作为第二个参数（ cash ），以及现金抽屉（ cid ）作为第三个参数。 cid是列出可用货币的2D数组。 checkCashRegister()函数应始终返回带有status键和change键的对象。返回{status: "INSUFFICIENT_FUNDS", change: []}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{status: "CLOSED", change: [...]}使用cash-in-drawer作为密钥change的值，如果它等于更改到期。否则，返回{status: "OPEN", change: [...]} ，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change密钥的值。如果卡住，请记得使用Read-Search-Ask 。尝试配对程序。编写自己的代码。 | 货币单位 | 量 |
