In this tutorial, you will learn what a double ended queue (deque) is. Also, you will find working examples of different operations on a deque in C, C++, Java and Python.
data structuresheappriority dequeA simple pointer-free data structure is proposed to implement priority deques. The two heaps (a min-heap and a max-heap) of a twin-heap are stored in one linear array. The simple parent-child relationship of a traditional heap is retained. The min-heap and...

A "deque" is a data structure consisting of a list of items, on which the following operations are possible: Push(X,D): Insert item X on the front end of deque D. Pop(D): Remove the front item from deque D and return it.
