[description of the problem]
Design a demonstration program to realize the addition operation of unary sparse polynomials.
[basic requirements]
(1) the input and establishment of two polynomials;
(2) polynomial A is added to B, and polynomial C is established.
(3) output polynomials a, B, C. Output format: for example, polynomial A is A (x) =c1xe1+c2xe2+... + cmxem, where Ci and EI are the coefficients and exponents of item I respectively, and each is arranged according to the exponent ascending power, that is, 0 or less E1 < E2 <... Em. Polynomial B, C is similar to output.
