Suppose that the number for floating point operations (flops) for the following functions (i. e., algorithms) have been estimated as:
(a) f(n) : 2n + 3n flops
(b) g(n): n! +2n logn +n2 flops
(c) h(n): (6+3n +n2)(n log n) flops
write down the time complexity of each function in o-notation.

Consider the following code snippet: #ifndef cashregister_h#define cashregister_hconst double max_balance = 6000000.0; class cashregister{public: cashregister(); cashregister(double new_balance); void set_balance(double new_balance); double get_balance() const; private: double balance[12]; }; double get_monthly_balance(cashregister bk, int month); #endifwhich of the following is correct? a)the header file is correct as given.b)the definition of max_balance should be removed since header files should not contain constants.c)the definition of cashregister should be removed since header files should not contain class definitions.d)the body of the get_monthly_balance function should be added to the header file.
