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

Input

The first line contains an integer t (1 ≤ t ≤ 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 ≤ a, b ≤ 1000).

Output

Print t integers — the required numbers a+b.
