利用线性表实现一个一元多项式Polynomial f(x) = a0 + a1x + a2x2 + a3x3 + … + anxn -The realization of a linear form of Multinomial Polynomial f (x) = a0+ a1x+ a2x2+ a3x3+ ...+ anxn

一元多项式A = anxn + … + a1x + a0, B = bnxn + … + b1x + b0，根据运算符+、-、*，分别计算A + B、A - B、A * B。-A polynomial A = anxn+ ...+ a1x+ a0, B = bnxn+ ...+ b1x+ b0+ operator,-,*, respectively, to calculate the A,+ B, A- B, A* B.
