1. Inserting an Element into the Priority Queue Inserting an element into a priority queue (max-heap) is done by the following steps. Insert the new element at the end of the tree. Insert an element at the end of the queue Heapifythe tree. ...
When we insert item into queue, we have to assign priority value with it. It will delete the highest priority element at first. To implement priority queue one of the easiest method is using the heap data structure. Let us see one C++ code for priority queue STL. Here the priority is ...
