• Define a Scheme function "flattenRev" which takes a list of lists of numbers, arbitrarily nested, and returns the flat list of the numbers present in it, but with inverted positions.                                            
  

                 Ex: (flattenRev (list (list 1 2 (list 3 4) 5) 6 7 (list 8 9))) --> (9 8 7 6 5 4 3 2 1)

• Define in Haskell the data type IntegerNumber (assuming it is not predefined).

• What is the precedence relation induced by a Scheme function definition?
