Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.A priority queue is an abstract data type in computer programming that supports the following three operations: insertWithPriority: add an element to the queue with an associated priority; getNext: remove the element from the queue that has the highest priority, and return it (also known as "PopElement(Off)", or "GetMinimum"); peekAtNext (optional): look at the element with highest priority without removing it. One can imagine a priority queue as a modified queue, but when one would get the next element off the queue, the highest-priority one is retrieved first. Stacks and queues may be modeled as particular kinds of priority queues. In a stack, the priority of each inserted element is monotonically increasing; thus, the last element inserted is always the first retrieved. In a queue, the priority of each inserted element is monotonically decreasing; thus, the first element inserted is always the first retrieved.
