A deque with heap order is a data structure consisting of a list of items, on which the following operations are possible: push(x): Insert item x on the front end of the deque.
pop(): Remove the front item from the deque and return it.
inject(x): Insert item x on the rear end of the deque.
eject(): Remove the rear item from the deque and return it.
findMin(): Return the smallest item from the deque (breaking ties arbitrarily).
1.a. Describe how to support these operations in constant amortized time per operation.
2.**b. Describe how to support these operations in constant worst-case time per operation.

1)consider the following code snippet: #ifndef book_h#define book_hconst double max_cost = 1000.0; class book{public: book(); book(double new_cost); void set_cost(double new_cost); double get_cost() const; private: double cost; }; double calculate_terms(book bk); #endifwhich of the following is correct? a)the header file is correct as given. b)the definition of max_cost should be removed since header files should not contain constants. c)the definition of book should be removed since header files should not contain class definitions. d)the body of the calculate_terms function should be added to the header file.
