Question

我需要一些帮助。我正在freecodecamp“收银机”上做篝火晚会。我的代码应该工作，因为它返回的是freecodecamp的要求，但是由于某些原因，即使两个答案相同，它也表示我的代码是错误的。有人可以看一下我的代码，让我知道哪里出了问题吗？

      let cashValue = [
        {name:"ONE HUNDRED", value:100},
        {name:"TWENTY", value:20},
        {name:"TEN", value:10},
        {name:"FIVE", value:5},
        {name:"DOLLAR", value:1},
        {name:"QUARTER", value:0.25},
        {name:"DIME", value:0.1},
        {name:"NICKEL", value:0.05},
        {name:"PENNY", value:0.01}
       ]
     function checkCashRegister(price, cash, cid) {
       var change = cash -price;
       console.log(change);
       let total = parseFloat(cid.reduce((acc,next)=>{return acc + 
       next[1]},0.0)).toFixed(2);
       let changeStatus = {status:"", change:[],};

       if(total<change){
         return {status: "INSUFFICIENT_FUNDS", change: []};
       } else if(total == change){
         return  {status: "CLOSED", change: cid};
       } else {
         cid = cid.reverse();
         cashValue.forEach((next,index)=>{

      if(change >= next.value){
         let currentValue = 0.0;
         while(change>=next.value && cid[index][1]>=next.value){
             currentValue += next.value;
             change -= next.value;
             change = Math.round(change * 100)/100;
             cid[index][1] -=next.value;
         }
         changeStatus.status = "OPEN";
         changeStatus.change.push([next.name,currentValue]);
       }
    });
   }        //console.log(change);

    if(change !== 0){
      changeStatus.status = "INSUFFICIENT_FUNDS";
      changeStatus.change = [];
    }
      return changeStatus;
    }

      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]]}

Answer 1

是的，您的代码很好。在这里，我从控制台日志中复制了它。

change 96.74

0: (2) ["TWENTY", 60]
1: (2) ["TEN", 20]
2: (2) ["FIVE", 15]
3: (2) ["DOLLAR", 1]
4: (2) ["QUARTER", 0.5]
5: (2) ["DIME", 0.2]
6: (2) ["PENNY", 0.04]

尝试将单打的变量名从DOLLAR更改为ONE，就像Johnny所说的那样，您应该通过...

收银机-我的代码应该可以正常工作，因为它返回的是freecodecamp要求的内容，但是由于某种原因，它表示我的代码是错误的
