Fee Calculation

This project was generated with Angular CLI version 12.2.6, NGRX version 12.4.0.

Task

Situation

Paysera users can go to a branch to cash in and/or cash out from Paysera account. There are also commission fees for both cash in and cash out. Only supported currency is EUR.

Commission Fees

For Cash In

Commission fee - 0.03% from total amount, but no more than 5.00 EUR.

You can get configuration from API

For Cash Out

There are different commission fees for cash out for natural and legal persons.

Natural Persons

Default commission fee - 0.3% from cash out amount.

1000.00 EUR per week (from monday to sunday) is free of charge.

If total cash out amount is exceeded - commission is calculated only from exceeded amount (that is, for 1000.00 EUR there is still no commission fee).

You can get configuration from API

Legal persons

Commission fee - 0.3% from amount, but not less than 0.50 EUR for operation.

You can get configuration from API

Rounding

After calculating commission fee, it's rounded to the smallest currency item (for example, for EUR currency - cents) to upper bound (ceiled). For example, 0.023 EUR should be rounded to 3 Euro cents.

Input data

Input data is given in JSON file. Performed operations are given in that file. In each object following data is provided:

{
    "date": "2016-01-05", // operation date in format `Y-m-d`
    "user_id": 1, // user id, integer
    "user_type": "natural", // user type, one of “natural”(natural person) or “juridical”(legal person)
    "type": "cash_in", // operation type, one of “cash_in” or “cash_out”
    "operation": {
        "amount": 200, // operation amount(for example `2.12` or `3`)
        "currency": "EUR" // operation currency `EUR`
    }
}

All operations are ordered by their date ascendingly.

Expected Result

As a single argument program must accept a path to the input file.

Program must output result to stdout.

Result - calculated commission fees for each operation. In each line only final calculated commission fee must be provided without currency.
