To try and encourage more sales of the 5 different Harry
Potter books they sell, a bookshop has decided to offer
discounts of multiple-book purchases.

One copy of any of the five books costs 8 EUR.

Your mission is to write a piece of code to calculate the
price of any conceivable shopping basket (containing only
Harry Potter books), giving as big a discount as possible.


If, however, you buy two different books, you get a 5%
discount on those two books.
