A set also has logarithmic insertions, and automatically does binary searches when you do lookups in it. You're over-complicating it, and that's not what priority queues are for. The standard library has loads of containers that do exactly what you want, priority queue is not one of them. – Jonathan Wakely May 11, 2016 at 16:00 http://duoduokou.com/algorithm/50847062200281020251.html

WebA binary heap is one of the most common ways of implementing a priority queue. So just by definition a max binary heap is a binary tree where each node has zero, one, or two … WebNote that a heap differs from a binary search tree in two significant ways. First, while a binary search tree keeps all the nodes in a sorted arrangement, a heap is ordered in a much weaker sense. Conveniently, the manner in which a heap is ordered is actually enough for the efficient performance of the standard priority queue operations.

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. Following are the principal methods of a Priority Queue.
