2.     For OJ submission:

Step 1. Submit only your function.cpp into the submission block. (***Note that you don’t need to submit your function.h.)

Step 2. Check the results and debug your program if necessary.

​

Input

There are four lines.

The first two lines represent the greatest power and the corresponding coefficients of the first polynomial.

The last two lines represent the greatest power and the corresponding coefficients of the second polynomial.

Note that the coefficients are in descending order and each element is separated by a blank.

Output

Your program should print the coefficients of the sum, difference and product of these two polynomials in descending order, respectively.

Note that every answer should be followed by a new line character.
