Challenge: Exact Change.

Question

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.

Return the string "Insufficient Funds" if cash-in-drawer is less than the change due. Return the string "Closed" if cash-in-drawer is equal to the change due.

Otherwise, return change in coin and bills, sorted in highest to lowest order.

EXAMPLES:

checkCashRegister(3.26, 100.00,
[["PENNY", 1.01], ["NICKEL", 2.05], ["DIME", 3.10], ["QUARTER", 4.25],
["ONE", 90.00], ["FIVE", 55.00], ["TEN", 20.00], ["TWENTY", 60.00],
["ONE HUNDRED", 100.00]]);

// should return [["TWENTY", 60.00], ["TEN", 20.00], ["FIVE", 15.00], ["ONE", 1.00],
["QUARTER", 0.50], ["DIME", 0.20], ["PENNY", 0.04]]

checkCashRegister(19.50, 20.00, [["PENNY", 0.01], ["NICKEL", 0], ["DIME", 0], ["QUARTER", 0], ["ONE", 1.00], ["FIVE", 0], ["TEN", 0], ["TWENTY", 0], ["ONE HUNDRED", 0]])
//should return "Insufficient Funds".

checkCashRegister(19.50, 20.00, [["PENNY", 0.50], ["NICKEL", 0], ["DIME", 0], ["QUARTER", 0], ["ONE", 0], ["FIVE", 0], ["TEN", 0], ["TWENTY", 0], ["ONE HUNDRED", 0]])
//should return "Closed".

Have Fun!

Answer 1

Here's my C# implementation! ✌

This is probably the longest code I've written in SoloLearn so far and I'm happy to complete the challenge! I've tried to use appropriate data structures offered by C# and make it as clean as possible.

Thank you for the challenge and I hope somebody will enjoy reading my code~
