Problem:
A + B Problem

Compute A + B.

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. The input will be terminated by EOF.

Output

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

Constraints

-1000 ≤ A, B ≤ 1000

Sample Input

1 2
10 5
100 20

Output for the Sample Input

3
15
120

Sample Program

#include<stdio.h>

int main(){
int a, b;
while( scanf("%d %d", &a, &b) != EOF ){
printf("%d\n", a + b);
}
return 0;
}

Solution in C (judge verdict: Time Limit Exceeded)

#include <stdio.h>

int main (){
    int A,B,i,total;
    i = -1000;
    while(i <= A, B <= 1000!=EOF){
        scanf ("%d %d",&A,&B);
        total = A + B;
        printf ("%d\n",total);
        i++;
    }
    return 0;
}
