Problem Description

Your task is to Calculate a + b.
Too easy?! Of course! I specially designed the problem for acm beginners.
You must have found that some problems have the same titles with this one, yes, all these problems were designed for the same aim.

 

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 5
10 20

JGShining   |   We have carefully selected several similar problems for you:   1090  1091  1092  1093  1094


如果你打的这个代码：

#include<stdio.h>
int main(){
	int a,b;
	while(EOF){
		scanf("%d%d",&a,&b);
		printf("%d\n",a+b);
	}
	return 0;
}

超时了对吧？？改一改就好了：
AC:

#include<stdio.h>
int main(){
	int a,b;
	while(scanf("%d%d",&a,&b)!=EOF){
		printf("%d\n",a+b);
	}
	return 0;
}
