说明

This problem is a little more difficult than the last one.

But I think that it is still very simple for clever you.

In this problem,you will get two integers A and B，and wants you to calculate the answer C，which equals to A add B.

输入格式

Input contains an integer N in the first line, and then N（$N \leq 1000$） lines follow. Each line consists of a pair of integers A and B, separated by a space, one pair of integers per line.($ 0\leq A, B\leq 1000$)

输出格式

For each pair of input integers A and B you should output the sum of A and B in one line, and with one line of output for each line in input.
