| 3 | +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. |
| 4 | + |
| 5 | +cid is a 2D array listing available currency. |
| 6 | + |
| 7 | +The checkCashRegister() function should always return an object with a status key and a change key. |
| 8 | + |
| 9 | +Return {status: "INSUFFICIENT_FUNDS", change: []} if cash-in-drawer is less than the change due, or if you cannot return the exact change. |
| 10 | + |
| 11 | +Return {status: "CLOSED", change: [...]} with cash-in-drawer as the value for the key change if it is equal to the change due. |
| 12 | + |
| 13 | +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. |
