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: Wrong Answer)

var readline = require("readline");
var rl = readline.createInterface({
    input : process.stdin,
    output: process.stdout
});

rl.on("line", function(text) {
    var reg = /([\d]+) ([\d]+)/;
    var data = reg.exec(text);

    if(data !== null && data.length === 3) {
        var a = parseInt(data[1]);
        var b = parseInt(data[2]);
        console.log(a + b);
    }
});
