 -- Question 6
--- How would you write the prod function from our lesson so that it works for Int and Double? Does the code compile?
-
--- You can write it as following. But you need to use a type class constraint in the type signature of your function.
--- The constraint is the "Num a =>" that tells haskell "a" can be only of certain types that implement the Num class 
--- for which the multiplication function (*) is defined. Without this, the compilation would give an error. We will 
--- learn more about type classes in lesson "Intro to type classes".

--- Question 7
 -- Can you also define in Haskell list of lists? Did we showed any example of that? How would you access the inner
