Design a cash register drawer function checkCashRegister() that accepts purchase price as the first argument (price), payment as the second argument (cash), and cash-in-drawer (cid) as the third argument.

cid is a 2D array listing available currency.

The `checkCashRegister()` function should always return an object with a status key and a change key.

Return `{status: "INSUFFICIENT_FUNDS", change: []}` if cash-in-drawer is less than the change due, or if you cannot return the exact change.

Return `{status: "CLOSED", change: [...]}` with cash-in-drawer as the value for the key change if it is equal to the change due.

Otherwise, return `{status: "OPEN", change: [...]}`, with the change due in coins and bills, sorted in highest to lowest order, as the value of the change key.

To sovle this problem we use a greedy algorithm. Starting from the largest value, we pass through the cid array and check if we can subtract this value from the changeValue and have a positive outcome.

To successfully add or subtract two decimal numbers it is necessary to use [Math.round()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/round).
