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).

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.

WebJan 25, 2024 · A heap is in fact a complete binary tree, so it is always as balanced as it can be: the leaves will always be positioned in the last or one-but-last level. A self-balancing BST (like AVL, red-black,...) cannot beat that high level of balancing, where you will often have leaves occurring at three levels or even more. highland cow bookmarkWebConstruct a priority queue using a heapordered binary tree, but instead of an array, use a triply linked structure.
