A plus B
This problem is intended as an introduction to the submission and judging system. For a detailed write-up of how to process input and output in your language of choice, see algocoding.wordpress.com/2015/04/23/fast-io-methods-for-competitive-programming/.
All input and output should be done using the standard input and output streams respectively.
The first line will contain an integer \(N\) (\(1 \leq N \leq 10^5\)). The next \(N\) lines will each contain a pair of space-separated integers whose absolute value is less than \(10^9\).
Output \(N\) lines each containing a single integer: The sum of each pair of integers from the input, in the same order as they are given.
