use std::io::{self, *};

fn main() {
    for line in io::stdin().lock().lines() {
        let line = line.unwrap();
        let mut it = line.split_whitespace();
        let a: i32 = it.next().unwrap().parse().unwrap();
        let b: i32 = it.next().unwrap().parse().unwrap();

        if a == 0 && b == 0 {
            break;
        }

        println!("{}", a + b);
