You are given two integers A and B. Your task is to compute their sum A + B and print the result.

However, there’s a twist! The numbers can be very large, so you must ensure your solution handles large inputs efficiently.

Input: The first line contains a single integer T (1 ≤ T ≤ 1000) — the number of test cases.

Each of the next T lines contains two integers A and B (−10^18 ≤ A, B ≤ 10^18).

Output: For each test case, print the sum A + B on a new line.
