1090 A+B for Input-Output Practice (II) :题目有N个输入组，接下来依次给出N个输入组数据

Problem Description
Your task is to Calculate a + b.
 
Input
Input contains an integer N in the first line, and then N lines follow. Each line consists of a pair 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
2
1 5
10 20

Sample Output
6
30
