计算两个以单链接表表示的多项式相乘的程序。

两个多项式相乘， 如p1(m项)，p2（n项），只需将后一多项式的各项与前一多项相乘，得到n个新的多项式，新的多项式产生后立即累加到一个备用的多项式即可。-Calculating two single linked list representation of polynomial multiplication process. Multiplying two polynomials, such as p1 (m items), p2 (n items), just after a polynomial multiplying the number of the previous one, get a new polynomial of n, the new polynomial generator accumulate immediately after a polynomial can alternate.
