Answer to Question #188440 in Python for Hari nadh babu

Question

Add two polynomials

Given two polynomials A and B, write a program that adds the given two polynomials A and B

Output

Print the addition of polynomials A and B.

If the degree of polynomial is zero and the constant term is also zero, then just print 0 to represent the polynomial.

For term Cix^Pi, if the coefficient of the term Ci is 1, simply print x^Pi instead of 1x^Pi.Explanation
