what is mean by d-queue?

Answer Posted / baskar

d-queue stands for double ended queue.we can add & delete
elements at either side.they are two other variations like
input restricted deque and output restricted deque.
Input restricted deque means we can delete at both end
but insert only at end of the queue(ie) rear .
Output restricted deque means we can insert at both end
but delete only at end of the queue(ie)front.
