对OJ题目一个总结（一）

（1）计算A+B
输入：输入是两个int型整数，用空格隔开，每两个是一对
输出：每一对输出一个结果，一个结果处于一行
Input
The input will consist of a series of pairs of integers a and b, separated by a space, one pair of integers per line.

Output
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.

Sample Input
1 2
3 4
5 6

Sample Output
3
7
11
