How can a polynomial in two variables(x,y) be represented by any linked list forms(types)? Each node should represent a term and should contain the powers of x, and y as well as the coefficient of that term, write C++ functions to do the following
a. Add two such polynomials.
b. Multiply two such polynomials.
c. Evaluate such a polynomial for given values of x,and y.
d. Print the representation of such a polynomial.
