Statement : The integrated steel plants in India would no longer have to depend on imports for continuous casting refractories.

Assumptions :
I. Continuous casting refractories are needed by India.
II. Continuous casting refractories are in demand.
Faster rate of drying of moulded refractories results in high __________ of refractories.
Silica refractories are also known as ______ refractories.

A Double-ended queue supports operations such as adding and removing items from both the sides of the queue. They support four operations like addFront(adding item to top of the queue), addRear(adding item to the bottom of the queue), removeFront(removing item from the top of the queue) and removeRear(removing item from the bottom of the queue). You are given only stacks to implement this data structure. You can implement only push and pop operations. What are the total number of stacks required for this operation?(you can reuse the stack)
