SortedPolynomial stores terms of a polynomial in sorted manner. All methods and operations keep it sorted.
This class inherits and implements PolynomialInterface.
coefficients can be any dict initial values. Optionally _sorted can be True if the coefficients is already sorted.
Return the degree of this polynomial.
Return the leading coefficient.
Return the leading term as a tuple (degree, coefficient).
Multiplication of two polynomials in the same ring. Computation is carried out by Karatsuba method.
