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 JavaScript (judge verdict: Accepted)

(function(stdin) {
'use strict';

  var inputs = stdin.toString().trim().split('\n');
  var lines  = inputs.map(function(v) {
    return v.split(' ').map(Number);
  });
  var result = (function(lines) {

    return lines.map(function add(v) {
      return v[0] + v[1];
    }).join('\n');

  })(lines);

  console.log(result);
})(require('fs').readFileSync('/dev/stdin', 'utf8'));
