This time, you are supposed to find A+B where A and B are two polynomials.
Input
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
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.

dict1 = {}for i in range(2): list1 = raw_input().split() for j in range(int(list1[0])): a = int(list1[j*2+1]) b = float(list1[j*2+2]) if a in dict1.keys(): dict1[a] += b if abs(dict1[a]) < 0.00001: del(dict1[a]) else: dict1[a] = bprint len(dict1),items = dict1.keys()items.sort()for item in reversed(items): print "%d %.1f" % (item, dict1[item]),
