)a grad student comes up with the following algorithm to sort an array a[1..n] that works by first sorting the first 2/3rds of the array, then sorting the last 2/3rds of the (resulting) array, and finally sorting the first 2/3rds of the new array. 1: function g-sort(a, n) . takes as input an array of n numbers, a[1..n] 2: g-sort-recurse(a, 1, n) 3: end function 4: function g-sort-recurse(a, `, u) 5: if u Γ’β ` Γ’β°Β€ 0 then 6: return . 1 or fewer elements already sorted 7: else if u Γ’β ` = 1 then . 2 elements 8: if a[u] < a[`] then . swap values 9: temp Γ’β a[u] 10: a[u] Γ’β a[`] 11: a[`] Γ’β temp 12: end if 13: else . 3 or more elements 14: size Γ’β u Γ’β ` + 1 15: twothirds Γ’β d(2 Γ’β size)/3e 16: g-sort-recurse(a, `, ` + twothirds Γ’β 1) 17: g-sort-recurse(a, u Γ’β twothirds + 1, u) 18: g-sort-recurse(a, `, ` + twothirds Γ’β 1) 19: end if 20: end function first (5 pts), prove that the algorithm correctly sorts the numbers in the array (in increasing order). after showing that it correctly sorts 1 and 2 element intervals, you may make the (incorrect) assumption that the number of elements being passed to g-sort-recurse is always a multiple of 3 to simplify the notation (and drop the floors/ceilings).

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.

Write a class that represents a polynomial. the constructor polynomial ( double c = 0.0 ); creates a polynomial that corresponds to p(x) = c. the method int degree (); returns the degree of the polynomial. (for the purpose of this assignment, letβs say the zero polynomial p(x) = 0 has degree 0.) the method int nonzeroterms (); returns the number of nonzero terms of the polynomial. for example, x 4 + 1 has 2 nonzero terms. the procedure void setcoeff (int deg , double c ); sets the coefficient of the term x deg to c. calling this function can increase or decrease the degree of the polynomial. assert that deg is nonnegative
