Extreme Carpaccio

Technical Instructions

Go to the clients directory and chose your client or create your own one
Go to the sellers view and register yourself (URL example: http://192.168.1.12:8080/)

The server will start sending orders like this:

POST /order HTTP/1.1
{
    "prices": [65.6,27.26,32.68],
    "quantities": [6,8,10],
    "country": "IE",
    "reduction":"STANDARD"
}

You should calculate the total and answer with an object bill, i.e.: { "total": 1000.0 } (the server checks responses using two decimal digits of precision, so, i. e., 10.1234 and 10.12 are equal).
Your score will be shown in the dashboard

The server will send you feedback like this:

POST /feedback HTTP/1.1
{
    "type": "ERROR",
    "content": "The field \"total\" in the response is missing."
}

Functional Instructions

To calculate the bill, you need to consider the tax of the country from which the order came from and the reduction.

Taxes

Here is the tax table used in the exercise:

Country	Code	Tax
Germany	DE	20%
United Kingdom	UK	21%
France	FR	20%
Italy	IT	25%
Spain	ES	19%
Poland	PL	21%
Romania	RO	20%
Netherlands	NL	20%
Belgium	BE	24%
Greece	EL	20%
Czech Republic	CZ	19%
Portugal	PT	23%
Hungary	HU	27%
Sweden	SE	23%
Austria	AT	22%
Bulgaria	BG	21%
Denmark	DK	21%
Finland	FI	17%
Slovakia	SK	18%
Ireland	IE	21%
Croatia	HR	23%
Lithuania	LT	23%
Slovenia	SI	24%
Latvia	LV	20%
Estonia	EE	22%
Cyprus	CY	21%
Luxembourg	LU	25%
Malta	MT	20%

For the order {"prices":[15.99],"quantities":[1],"country":"ES","reduction":"STANDARD"}, for example, the response should be {"total":19.03}.

Reductions

Following the STANDARD reductions applied for the most part of the orders:

Total	Reduction

= 50 000 EUR | 15 % = 10 000 EUR | 10 % = 7 000 EUR | 7 % = 5 000 EUR | 5 % = 1 000 EUR | 3 %

For the order {"prices":[4.1,8.03,86.83,65.62,44.82],"quantities":[10,3,5,4,5],"country":"AT","reduction":"STANDARD"}, for example, the response should be {"total":1166.62}.

Note that:

reductions are applied after the taxes;
another reduction types can appear during the game. You need to stay tuned in the server's feedback to figure out how to calculate it.
