;; Treap accessible by index (O(log(n))).
;; Virtually it works like std::set of C++ or TreeSet of Java. 

;; Note:
;; - You shouldn't insert duplicate keys into a treap unless you know what you
;; are doing.
;; - You cannot rely on the side effect when you call any destructive operations
;; on a treap. Always use the returned value.
;; - An empty treap is NIL.
