A+B for Input-Output Practice (III)

Problem Description

Your task is to Calculate a + b.

 

Input

Input contains multiple test cases. Each test case contains a pair of integers a and b, one pair of integers per line. A test case containing 0 0 terminates the input and this test case is not to be processed.

 

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

1 510 200 0

 

Sample Output

630

my answer(accepted):

import java.util.Scanner;public class hd1091 {public static void main(String[] args) {Scanner scan=new Scanner(System.in);while(scan.hasNext()){int a=scan.nextInt();int b=scan.nextInt();if(a==0&&b==0){return;}System.out.println(a+b);}}}
