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

#include <stdio.h>
int main (void)
{
	int n;
	int a,b;
	scanf("%d",&n);//数据组数
	while(n--)
	{
		scanf("%d%d",&a,&b);
		printf("%d\n",a+b);	//输出换行
	}	
	return 0;
}
