The fold functions compute a value over a list (or some other type that is foldable) by applying an operator to the list elements and a neutral element. The foldl function assumes that the operator is left associative, the foldr function assumes that the operatore is right associative. For example, the function application foldl (+) 0 [3,5,2,1] 1 results in the computation of (((0+3)+5)+2)+1) and the function application foldr (+) 0 [3,5,2,1] 1 results in the computation of (3+(5+(2+(1+0)). The value computed by the fold functions may be more complex than a simple scalar. It is very well possible to construct a new list as part of the fold. For example: map' :: (a -> b) -> [a] -> [b] map' f xs = foldr ((:) . f) [] xs 1 The evaluation of map' succ [1,2,3] results in the list [2,3,4]. There are several duality theo- rems that can be stated for fold functions. Prove the following three duality theorems: a) Let op be an associative operation with e as the neutral element: op is…

4. Prove that, if f : A → B has an inverse, then f is bijective. (The converse is also true, and very useful, but you do not need to prove it.) If A is a set, a binary operation on A is a function 3: Ax A→ A. Binary operations are ubiquitous in modern algebra, and their appearance there motivates the following notation: for (a1, a2) € A × A, we write a₁ßa2 instead of the usual functional notation B(a₁, a2) for the image of (a₁, a2) under 3. The most important (and motivating) instances of this (very general) notion for us are the addition and multiplication operations on a ring.
