Cash Register challenge needs explanation

JavaScript
#1

hello , i am trying to solve challenge " Cash Register", and i solved some of its scenarios but i am stuck in these two scenarions i can’t understand this one, can any one explain this case for me please ?

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]]} .

To receive help, please provide your code.

This says that you should get 50cents change when you pay with $20 and only $19.50 is due.

hi Jermey,

this is my code, but i still thinking about logic for case i posted

function checkCashRegister(price, cash, cid) {
 
  var change= cash - price; 
  var totalCID=0;
  var obj;
  

///calculating total in drawer
 for (var i=0;i<cid.length;i++)
  {
   
      totalCID += cid[i][1];
  }



if (totalCID < change || totalCID>=1)
 {
   obj= {status: "INSUFFICIENT_FUNDS", change: []};
 } 

 else if (totalCID === change)
 {
   obj= {status: "CLOSED", change: cid };
 }

 else 
 { /// still thinking about this scenario
   object = {status: "OPEN", change:cid};
 }
 
return obj;

} ```

I mean why it returned value of “QUARTER” only not another value , although the requirement was to return {status: "OPEN", change: [...]} , with the change due in coins and bills, sorted in highest to lowest order.

same for this scenario

checkCashRegister(3.26, 100, [["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: [["TWENTY", 60], ["TEN", 20], ["FIVE", 15], ["ONE", 1], ["QUARTER", 0.5], ["DIME", 0.2], ["PENNY", 0.04]]} .

why it didn’t return [“ONE HUNDRED”, 100]] in the returned sorted array??

Only 50 cents in quarters is the expected change.

In the second case you mention, a 100 dollar bill is not part of the change being given back.
