说明：  多项式相乘一元稀疏多项式简单计算器的基本功能是： （1)输入并建立多项式； （2）输出多项式，输出形式为整数序列：n,c1,e1,c2,e2,...,cn,en,其中n是多项式的项数，ci和ei分别是第i项的系数和指数，序列按指数降序排列。 （3）多项式a与多项式b相乘，建立多项式。
(Sparse polynomial multiplication unary polynomial basic functions of the calculator is simple: (1) input and the establishment of polynomial (2) the output polynomial, the output in the form of an integer sequence: n, c1, e1, c2, e2 ,..., cn, en, where n is the number of items polynomial, ci and ei is the first i entries are the coefficient and the index sequence in descending order by index. (Three) polynomial a polynomial b multiplied with the establishment of polynomials.)
