WebA priority queue is a powerful tool that can solve problems as varied as writing an email scheduler, finding the shortest path on a map, or merging log files. Programming is full of optimization problems in which the goal is to find the best element. Priority queues and the functions in the Python heapq module can often help with that. WebHello. In this lesson we will consider binary heaps in full detail. A 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 children where the following property is satisfied for each node.

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. Web1.35%. From the lesson.
