Consider the following binary tree method for a tree with keys of type Key, which is an object type. public boolean mystery () { return mystery (root, null, null); private boolean mystery (Node x, Key a, Key b) { } if (x == null) return true;B if (a != null && x.key.compareTo(a) <= 0) return false; if (b != null && x.key.compareTo(b) >= 0) return false; return mystery (x.left, a, x.key) && mystery (x.right, x.key, b); (a) In plain English, describe the function of mystery (). (This should be a short, clear answer. Zero credit for describing the code line by line!)
