# Pete likes to bake some cakes. He has some recipes and ingredients.
# Unfortunately he is not good in maths. Can you help him to find out,
# how many cakes he could bake considering his recipes?

# Write a function cakes(), which takes the recipe (object) and the available ingredients (also an object)
# and returns the maximum number of cakes Pete can bake (integer). For simplicity there are no units for
# the amounts (e.g. 1 lb of flour or 200 g of sugar are simply 1 or 200).
# Ingredients that are not present in the objects, can be considered as 0.

# Examples:

# must return 2
# cakes({flour: 500, sugar: 200, eggs: 1}, {flour: 1200, sugar: 1200, eggs: 5, milk: 200})
# must return 0
# cakes({apples: 3, flour: 300, sugar: 150, milk: 100, oil: 100}, {sugar: 500, flour: 2000, milk: 2000})


def cakes(recipe, available):
