Double-sided priority Queues using min-max heaps


How are the basic operations on a min-max heap implemented? They are insert(), deletemin(), deletemax(), findmin(), and findmax().

A queue must be defined as:

PriorityQueue {
     int Size;
     int Maxsize;
     int *Elements;
}

Where Size is the current size of the heap, MaxSize is its's capacity, *Elements is a pointer to an array that con hold Maxsize integers.

The web page did provide somewhat of a general overview of the subject and it's implementation and it was enough to get me started. Thanks!
