菜鸟记录PAT甲级1002--Polynomials

　　开始前有必要说一下，这才第二题就碰到了烂尾题，以自己开始的思路交了n次，错了n词，最后才19分，后来看了一下大佬的c++代码（尽然没有c的代码），还好c和c++的差别不是特别大，仔细琢磨一遍后突然发现很多地方可以改进，整理思路在此尝试终于AC，这才第二题啊。。。。

This time, you are supposed to findA+BwhereAandBare two polynomials.

Input Specification:

Each input file contains one test case. Each case occupies 2 lines, and each line contains the information of a polynomial:

KN1​aN1​​N2​aN2​​...NK​aNK​​

whereKis the number of nonzero terms in the polynomial,Ni​andaNi​​(i=1,2,⋯,K) are the exponents and coefficients, respectively. It is given that1≤K≤10，0≤NK​<⋯<N2​<N1​≤1000.

Output Specification:

For each test case you should output the sum ofAandBin one line, with the same format as the input. Notice that there must be NO extra space at the end of each line. Please be accurate to 1 decimal place.

Sample Input:

2 1 2.4 0 3.2
2 2 1.5 1 0.5
