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 ... WebPriority Queues with Binary Heaps. One important variation of the queue is the priority queue. A priority queue acts like a queue in that items remain in it for some time before being dequeued. However, in a priority queue the logical order of items inside a queue is determined by their “priority”. Specifically, the highest priority items ...
