如何在多费用分割的基础上对不同份额的用户进行费用分割？

Question

我想根据以下几点来分摊费用：

1. Expense By user.
2. Divided by users.
3. Share of each user.

我要输出谁欠其他用户的钱的用户列表。我试过用不同的方法计算，但没有任何帮助。

如果有人能帮上忙，会很感激的.

投入Json：

​

var expenseObj = [
  {
    expenseBy:{
      user:"A",
      amount:1000
    },
    dividedBy: [
      {
        user:"A",
        amount:100
      },{
        user:"B",
        amount:500
      },{
        user:"C",
        amount:400
      }
    ]
  },
  {
    expenseBy:{
      user:"B",
      amount:2000
    },
    dividedBy: [
      {
        user:"A",
        amount:1000
      },{
        user:"B",
        amount:400
      },{
        user:"C",
        amount:600
      }
    ]
  }
]

Answer 1

  for (let i = 0; i<expenseObj.length; i++){
      var share = expenseObj[i].expenseBy.amount/expenseObj[i].dividedBy.length;
      var addedBy = expenseObj[i].expenseBy.user;
      var addedAmount = expenseObj[i].expenseBy.amount;
      for(j=0; j<expenseObj[i].dividedBy.length;j++){
        var amount = share-expenseObj[i].dividedBy[j].amount
          if( amount >= 0){
            console.log(expenseObj[i].dividedBy[j].user+" owes "+amount+" in expense added by "+addedBy+" of amount "+addedAmount);
          }
      }
  }
