WebThe binary search tree becomes a priority queue if the sort order is based on priority. The time complexity to locate the top priority element is constant. We can keep an extra … 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.

WebMay 16, 2024 · For the priority queue in this article, we use a min heap because the highest priority is the one with the lowest number (priority 1 is usually higher than priority 2). Here is an example of what such a min-heap might look like: min-heap example. The element at each node of this tree is less than the elements of its two child nodes: 1 is less ...
