Add two polynomials
Given two polynomials A and B, write a program that adds the given two polynomials A and B.
Input
The first line contains a single integer M. Next M lines contain two integers Pi, Ci separated with space, where Pi denotes power and Ci denotes co-efficient of Pi for polynomial A. After that next line contains a single integer N. Next N lines contain two integers Pj, Cj separated with space, where Pj denotes power and Cj denotes co-efficient of Pj for polynomial B.
