PQ with an Array If we implement the PQ with an array, there are two main approaches: An unordered array and a sorted array. WebIn Priority queue items are ordered by key value so that item with the lowest value of key is at front and item with the highest value of key is at rear or vice versa. So we're assigned priority to item based on its key value. Lower the value, higher the priority.

WebThe classic data structure for priority queues is the "heap", a balanced binary tree in which the the key at any node is bigger than all the keys in nodes below it. With heaps, empty is constant time, insert and delete_max are logN time. But merge takes NlogN time, as one must take all the elements out of one queue and insert them into the other queue.
