【算法筆記】Product of Polynomials
his time, you are supposed to find?A+B?where?A?and?B?are 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:
K?N1?aN1?N2?aN2?...?NK?aNK
where?K?is the number of nonzero terms in the polynomial,?Ni?and?aNi?(i=1,2,?,K) are the exponents and coefficients, respectively. It is given that?1≤K≤10，0≤NK<?<N2<N1≤1000.
Output Specification:
For each test case you should output the sum of?A?and?B?in 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
結(jié)尾無空行
Sample Output:
3 2 1.5 1 2.9 0 3.2
結(jié)尾無空行
