Calculate 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.

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 2
3 4
5 6

Sample Output

Sample program

C/C++:

#include <stdio.h>
int main()
{
    int a, b;
    while (scanf("%d%d", &a, &b)==2)
    {
        printf("%d\n", a+b);
    }
    return 0;
}

JAVA:

import java.util.Scanner;

public class Main {
    public static void main(String args[]) throws Exception {
        Scanner scanner = new Scanner(System.in);

        while (scanner.hasNext()) {
            int a = scanner.nextInt();
            int b = scanner.nextInt();
            System.out.println(a + b);
        }
    }
}

PASCAL:

PROGRAM p1001; VAR a,b: Integer; BEGIN WHILE NOT EOF(input) DO BEGIN ReadLn(a,b); WriteLn(a+b) END END.
