Polynomial addition Onge Teacher C Programming Cap 7th Chapter programming problem

Topic content:

A polynomial can be expressed as the sum of the powers of x multiplied by the coefficients, for example:

2x6+3x5+12x3+6x+20

Now, your program reads in two polynomial, then outputs the sum of the two polynomial, which adds the coefficients of the corresponding powers and outputs them.

The maximum power to be processed by the program is 100.

Input format:

To enter a total of two polynomial, the input format for each polynomial is as follows:

Enter two numbers per line, the first represents a power, the second represents the power factor, and all the coefficients are integers. The first line must be the highest power, and the last line must be power 0 times.

Note that the first and last lines are not necessarily in the order of power reduction, if the coefficient of a power is 0, it does not appear in the input data, and the coefficient of 0 power is 0 o'clock or it appears in the input data.

Output format:

Starting at the highest power, descending to a power of 0, such as:

2x6+3x5+12x3-6x+20

Note that x is a lowercase x, and there are no spaces between all the symbols, and there is no need for a power with a factor of 0.

Input Sample:

6 2

5 3

3 12

1 6

0 20

6 2

5 3

2 12

1 6

0 20

Sample output:

4x6+6x5+12x3+12x2+12x+40
