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.
Currency Unit Amount
Penny $0.01 (PENNY)
Nickel $0.05 (NICKEL)
Dime $0.1 (DIME)
Quarter $0.25 (QUARTER)
Dollar $1 (ONE)
Five Dollars $5 (FIVE)
Ten Dollars $10 (TEN)
Twenty Dollars $20 (TWENTY)
One-hundred Dollars $100 (ONE HUNDRED)
See below for an example of a cash-in-drawer array:

["QUARTER", 4.25],

["ONE HUNDRED", 100]
