Hello @smuhammad !

What is the issue you are having?

3

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]]} .

the Said That I did Not Pass I most Finished This And I did My Best I can’t Solve It That Is Why i AM Looking For Help

Ok, so why do you think it isn’t passing? Are any of the tests passing?

5

Yes All Of The Test Are Passing But It Is The Only One That Its Not Passing

Can You Pls Help ME And Send Your Solution

Your code is returning:
{ status: ‘OPEN’,
change:
[ [ ‘TWENTY’, 60 ],
[ ‘TEN’, 20 ],
[ ‘ONE’, 16 ],
[ ‘QUARTER’, 0.5 ],
[ ‘DIME’, 0.2 ],
[ ‘PENNY’, 0.04 ] ] }

The desired output is:
{status: "OPEN", change: [["TWENTY", 60], ["TEN", 20], ["FIVE", 15], ["ONE", 1], ["QUARTER", 0.5], ["DIME", 0.2], ["PENNY", 0.04]]}

Indicating, that something is wrong in the code where you are making change.

SO WHere Would I Make The Change

As this is a certification project that you have written, I was hoping that you might be able to suggest something yourself. Giving you the solution is not within the spirit of this community and it would scarcely benefit man nor beast.

You are almost there and you should persist in acheiving the correct result. Suggest something constructive and I will be more than happy to help.

Try explaining the logic behind the code making change.
