Problem

Given two integers, calculate and print their sum.

Input

The input consists of several test cases. The first line contains an integer $t$ ( $t \le 100$ ), the number of test cases. Then $t$ test cases follow, each on its own line containing two space-separated integers $x$ and $y$ ( $-10^9 \le x, y \le 10^9$ ).

Output

For each test case, print the sum of the corresponding two integers on its own line.
