Suppose that you want to use a list data structure to implement a Set data type. Write insert and member operations in (a) Scheme; (b) ML; (c) Haskell. Make sure that in ML and Haskell your Set data type is distinct from a list. (d) In Haskell, define your Set type to be an instance of classes Eq and Show.
