A pizza place offers the following toppings:
- ham
- salami
- mushroom
- spinach
- artichoke
Create a function that generates all types of pizza that they can bake from the 5 toppings and calculates the price of each type of pizza. The name of the pizza should be made up of the chosen toppings in alphabetical order like "artichoke, ham and mushroom" (with "and" before the last element).
The pricing is as follows:
- pizza base: €8
- ham: €2
- salami: €3
- mushroom: €1
- spinach: €1
- artichoke: €2
Each pizza has 3 different toppings.
There should be 10 types of pizza.
Expected output (in alphabetical order):
artichoke, ham and mushroom - €13
artichoke, ham and salami - €15
artichoke, ham and spinach - €13
artichoke, mushroom and salami - €14
artichoke, mushroom and spinach - €12
artichoke, salami and spinach - €14
ham, mushroom and salami - €14
ham, mushroom and spinach - €12

mushroom, salami and spinach - €13
Each pizza has 3 toppings and any topping can be selected multiple times. If a topping is selected twice, it should be called "double". If a topping is selected three times, it should be called "triple". E.g. "double ham and spinach" instead of "ham, ham and spinach" and "triple ham" instead of "ham, ham and ham".
There should be 35 types of pizza.

artichoke and double ham - €14
