Notice that we have pushed elements in random order but when printing them we get the integers sorted in descending order:20,7,1. The top of the queue is the maximum element in the queue sincepriority_queueis implemented asmax-heapby default. Printing Queue Elements We cannot iterate through...
a company has three services: data query, email processing, and file transfer. The three services have different priorities. When HostA and HostB access servers of the three services, the services must be processed in descending order of priority. Priority re-marking and queue scheduling can achi...

To sort the records, this post uses last_updated_timestamp, which creates a priority queue based on an item’s timestamp. You can choose to sort in ascending or descending order. Depending on your business case, you can add any other attribute to implement your own priority mechanism. For...
The priority queue supports only comparable elements, which means that the elements are either arranged in an ascending or descending order. Note that, In Priority Queue: Every element in it has some priority associated with it either higher or lower. ...
