A priority queue is a queue where a numeric priority is associated with each element. Access to elements that have been inserted into the queue is limited to inspection and removal of the elements with smallest and largest priority only. A priority queue may have multiple items that are of equal priority. Give the ADT specification for a bounded priority queue using the specification method described in Topic 7 of the lecture notes. By "bounded", it is meant that the priority queue has a maximum capacity specified when it is created, and it can never contain more than that number of items. Your specification must specify the following operations: Page 3

Question
A priority queue is a queue where a numeric priority is associated with each element. Access to
elements that have been inserted into the queue is limited to inspection and removal of the elements
with smallest and largest priority only. A priority queue may have multiple items that are of equal
priority.
Give the ADT specification for a bounded priority queue using the specification method described
in Topic 7 of the lecture notes. By "bounded", it is meant that the priority queue has a maximum
capacity specified when it is created, and it can never contain more than that number of items.
Your specification must specify the following operations:
Page 3
newPriorityQueue: make a new queue
insert: inserts an element with a certain priority
isEmpty: test if the queue is empty
isFull: test if the queue is full
maxItem: obtain the item in the queue with the highest priority
minItem: obtain the item in the queue with the lowest priority
deleteMax: remove from the queue the item with the highest priority
deleteAllMax: remove from the queue all items that are tied for the highest priority
deleteMin: remove from the queue the item with the lowest priority
frequency: obtain the number of times a certain item occurs in the queue (with any priority)
