A pair of two very large positive integers is given. The task is to print their sum.
The first line of input contains a single integer T denoting the number of test cases. Then T test cases follow. Each test case consists of two lines. In the first line is the first number A and in the second is the second number B.
Corresponding to each test case, print the sum of A and B in a new line.
1 ≤ T ≤ 100
1 ≤ A,B ≤ 101002
