úÎ!}»     Policy type for a  Policy type for a . The 9 class defines an order on the elements contained within  a .  Compare two elements, just like  of the  class.  9The first parameter must be ignored by the implementation. A ; with inverted order: The maximum will be extracted first. A . which will always extract the minimum first.  The basic  type. O(1) . Is the  empty? O(1) . Is the  empty? O(1). Calculate the rank of a . 'Gets the default policy instance for a  that can be the first  parameter of . This function always returns  . O(n) . The number of elements in the . O(1)&. Finds the minimum (depending on the  ) of the . O(1). Constructs an empty . O(1). Create a singleton . O(log n). Insert an element in the . O(log n)'. Delete the minimum (depending on the )  from the . O(log n)%. Find the minimum (depending on the ) and  delete it from the . O(log max(n, m)). The union of two s. !Combines a value x and two Heaps to one . Therefore, x has to / be less or equal the minima (depending on the  ) of both   parameters. The precondition is not checked.  Builds the union over all given s.  Builds a  from the given elements.  You may want to use , if you have a sorted list. O(n). Lists elements of the  in no specific order. O(n). Lists elements of the  in no specific order. O(n) . Creates a , from an ascending list. Note that the list * has to be ascending corresponding to the  , not to it's  ) instance declaration (if there is one).  The precondition is not checked. O(n). Lists elements of the # in ascending order (corresponding  to the ). BSanity checks for debugging. This includes checking the ranks and M the heap and leftist (the left rank is at least the right rank) properties.
