I am trying to to understand why Java’s ArrayDeque is better than Java’s LinkedList as they both implement Deque interface. I hardly see someone using ArrayDeque in their code. If someone sheds more light into how ArrayDeque is implemented, it would be helpful. If I understand it, I will be more confident using it. I … Read more
I need a Stack data structure for my use case. I should be able to push items into the data structure and I only want to retrieve the last item from the Stack. The JavaDoc for Stack says : A more complete and consistent set of LIFO stack operations is provided by the Deque interface … Read more
I was looking at STL containers and trying to figure what they really are (i.e. the data structure used), and the deque stopped me: I thought at first that it was a double linked list, which would allow insertion and deletion from both ends in constant time, but I am troubled by the promise made … Read more

Python has at least two queue classes, Queue.Queue and collections.deque, with the former seemingly using the latter internally. Both claim to be thread-safe in the documentation. However, the Queue docs also state: collections.deque is an alternative implementation of … Read more
