Consider an ADT Polynomialin a single variable xwhose operations include: degree ()-Return the degree of a polynomial. int coefficient (unsigned exponent) - Return the coefficient of the term exponent set coefficient (int newcoefficient, unsigned exponent) Replace the coefficient of the term responent with newcoefficient print ()-Will convert a Polynomial object into a std::string object suitable for output using std::cout For this assignment, we will only consider polynomials with nonnegative, integral exponents and integral coefficients, i.e. coefficients can be negative. Notice that the interface to the ADT Polynomial only allows for exponents that are unsigned integers, that is, they must be nonnegative. For example: p= 4x + 723 - +9 The following demonstrates the ADT Polynomial's operations on the polynomial y above: p.degree() returns 5 (the highest exponent on a term with a nonzero coefficient) p.coefficient (3) returns 7 (the coefficient on the z term) p.coefficient (4) returns 0 (zero-the coefficient of a missing term is implicitly zero) p.setCoefficient (-3, 7) changes p to -3x7 + 4.05 + 703 - 2 + 9 std::cout
