Cash-Register

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:

[

["PENNY", 1.01],

["NICKEL", 2.05],

["DIME", 3.1],

["QUARTER", 4.25],

["ONE", 90],

["FIVE", 55],

["TEN", 20],

["TWENTY", 60],

["ONE HUNDRED", 100]

]

Tests

checkCashRegister(19.5, 20, [["PENNY", 1.01], ["NICKEL", 2.05], ["DIME", 3.1], ["QUARTER", 4.25], ["ONE", 90], ["FIVE", 55], ["TEN", 20], ["TWENTY", 60], ["ONE HUNDRED", 100]]) should return an object.

checkCashRegister(19.5, 20, [["PENNY", 1.01], ["NICKEL", 2.05], ["DIME", 3.1], ["QUARTER", 4.25], ["ONE", 90], ["FIVE", 55], ["TEN", 20], ["TWENTY", 60], ["ONE HUNDRED", 100]]) should return {status: "OPEN", change: [["QUARTER", 0.5]]}.
