## Description
<section id="description"> <code>checkCashRegister()</code> функцию ящика <code>checkCashRegister()</code> которая принимает цену покупки в качестве первого аргумента ( <code>price</code> ), платеж как второй аргумент ( <code>cash</code> ) и денежный ящик ( <code>cid</code> ) в качестве третьего аргумента. <code>cid</code> - это 2D-массив, в котором доступна доступная валюта. Функция <code>checkCashRegister()</code> всегда должна возвращать объект со <code>status</code> ключом <code>change</code> . Return <code>{status: &quot;INSUFFICIENT_FUNDS&quot;, change: []}</code> если сумма в ящике меньше, чем требуемое изменение, или если вы не можете вернуть точное изменение. Return <code>{status: &quot;CLOSED&quot;, change: [...]}</code> с наличным ящиком в качестве значения для <code>change</code> ключа, если оно равно требуемому изменению. В противном случае верните <code>{status: &quot;OPEN&quot;, change: [...]}</code> , с внесением изменений в монеты и счета, отсортированные в порядке наивысшего и наименьшего, в качестве значения ключа <code>change</code> .
