There is a need to have a simple data structure that can be used as a priority queue with low overhead. The data structure should have the operation where the data item with the minimum/maximum value is the next item to be deleted. The data structure should also support the function of...
Circular queue avoids the wastage of space in a regular queue implementation using arrays. In this tutorial, you will understand circular queue data structure and it's implementations in Python, Java, C, and C++.
Java PriorityBlockingQueue class is concurrent blocking queue data structure implementation in which objects are processed based on their priority. The “blocking” part of the name is added to imply the thread will block waiting until there’s an item available on the queue....
queue[rear] ← data return true end procedure C programming language implementation of the enqueue() function − int enqueue(int data) if(isfull()) return 0; rear = rear + 1; queue[rear] = data; return 1; Dequeue Operation It takes two steps to access data from a queue: first, ac...
Data Structure Quick reference Binary Heap Priority Queue This is the most common implementation but not the only one. Worst Case space O(n)O(n) peek O(1)O(1) dequeue O(lg(n))O(lg(n)) enqueue O(lg(n))O(lg(n)) A priority queue is a special queue where: Every ...
Improving PQ implementationCan we do better? We could do nothing after insertion O(1) and then delegate the finding of the element with the highest priority to dequeue (if max-heap). That would be O(n).O(n) as time complexity is not bad. It’s better than sorting all elements on ...
