Tell us what’s happening:
Hey guys, trying to finish up my last javascript challenge but having some issues with the final test case (when it should return status: “CLOSED”, change: […]). My output appears correct and the code passes all the other tests - I can’t quite figure out whats causing it to fail. Can anyone advise?
Your code so far
function checkCashRegister(price, cash, cid) {
var changeVal = [0.01, 0.05, 0.1, 0.25, 1, 5, 10, 20, 100];
var changeNames = ["PENNY", "NICKEL", "DIME", "QUATER", "DOLLAR", "FIVE", "TEN", "TWENTY", "ONE HUNDRED"];
var totalCID = 0;
var changeReq = cash - price;
var output = {status: "", change: []}
// Total Cash in Drawer;
for (let i = 0; i < cid.length; i++) {
totalCID += cid[i][1];
}
totalCID = (Math.round(totalCID * 100)) / 100;
// If not enough cash in drawer, return insufficient
if (totalCID < (cash - price)) {
output.status = "INSUFFICIENT_FUNDS";
return output;
} else {
// Work out the change due
for (let i = cid.length - 1; i >= 0; i--) {
let changeToAdd = 0;
let changeObj = [cid[i][0]];
//console.log(cid[i][1] + " - " + changeVal[i]);
//console.log(changeReq + " > " + changeVal[i] + " CID " + cid[i]);
if ((changeReq >= changeVal[i]) && (cid[i][1] > 0 )) {
while ((changeReq >= changeVal[i]) && (cid[i][1] > 0)) {
changeReq -= changeVal[i];
changeToAdd += changeVal[i];
cid[i][1] -= changeVal[i];
totalCID -= changeVal[i];
totalCID = Math.round(totalCID * 100) / 100;
cid[i][1] = Math.round(cid[i][1] * 100) / 100;
changeReq = Math.round(changeReq * 100) / 100;
}
}
if (changeToAdd > 0) {
changeToAdd = Math.round(changeToAdd * 100) / 100;
changeObj.push(changeToAdd);
output.change.push(changeObj);
}
}
}
// If not able to return correct change
if (changeReq != 0) {
output.status = "INSUFFICIENT_FUNDS";
output.change = [];
} else {
// If total cash required as change, set status to CLOSED + add extra
if (totalCID == 0) {
output.status = "CLOSED";
for (let j = 0; j < changeNames.length; j++) {
let checker = 0;
for (let x = 0; x < output.change.length; x++) {
if (output.change[x][0] == changeNames[j]) {
checker++
}
}
if (checker == 0) {
output.change.push([changeNames[j], 0]);
}
}
} else {
// Else set status to open, leave change as is
output.status = "OPEN";
}
}
console.log(output.status);
console.log(output.change);
return output;
}
// Example 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]]
checkCashRegister(19.5, 20, [["PENNY", 0.5], ["NICKEL", 0], ["DIME", 0], ["QUARTER", 0], ["ONE", 0], ["FIVE", 0], ["TEN", 0], ["TWENTY", 0], ["ONE HUNDRED", 0]]);
