Develop class Polynomial. The internal representation of a Polynomial is a dictionary of terms. Each term is a key–value pair that contains an exponent and a coefficient. The term 2x4 has the coefficient 2 and the exponent 4. For simplicity, assume the polynomial contains only nonne- gative exponents. Develop the class with a dictionary-based interface for accessing terms that includes the
following elements: a) The class’s constructor accepts a dictionary of exponent:coefficient pairs. b) Coefficient values in a Polynomial are accessed by exponent keys (e.g., polynomial[ exponent ] = coefficient). If a polynomial does not have a coefficient for a specified exponent, the expression polynomial[ exponent ] evaluates to 0. c) The length of a Polynomial is the value of its highest exponent. d) Define method __str__ for representing a Polynomial as a string with terms of the form cxy. e) Include an overloaded addition operator (+) to add two Polynomials. f) Include an overloaded subtraction operator (-) to subtract two Polynomials.
