10.12 It is conceivable that one linear structure is more general than another. (a) Is it possible to implement a Queue using a Stack? What is the complexity of each of the Queue operations? (b) Is it possible to implement a Stack using a Queue? What are the complexities of the various Stack methods? 10.13 Describe how we might efficiently implement a Queue as a pair of Stacks, called a “stack pair.” (Hint: Think of one of the stacks as the head of the queue and the other as the tail.)
