You are given two integers $$$a$$$ and $$$b$$$. Print $$$a+b$$$.

Input

The first line contains an integer $$$t$$$ ($$$1 \le t \le 10^4$$$) — the number of test cases in the input. Then $$$t$$$ test cases follow.

Each test case is given as a line of two integers $$$a$$$ and $$$b$$$ ($$$-1000 \le a, b \le 1000$$$).

Output

Print $$$t$$$ integers — the required numbers $$$a+b$$$.
