Use Clojure: a. The built-in function type is useful for checking what kind of object an expression evaluates to. Write a function both-same-type? that takes two arguments, and returns true when they both have the same type, and false otherwise. b. Write a function list-longer-than? which takes two arguments: an integer n, and a list lst and returns true if lst has more than n elements, and false otherwise. For example, (list-longer-than? 3 '(1 2 3)) should return false, and (list-longer-than? 2 '(1 2 3)) should return true.
