Calculate A + B and output the sum in standard format – that's, the digits must be separated to groups of three by COM Mas (unless there is less than four digits).

Input

Each input file contains the one test case. Each case contains a pair of integers a and b where-1000000 <= A, b <= 1000000. The numbers is separated by a space.

Output

For each test case, you should output the sum of A and B on one line. The sum must is written in the standard format. Sample Input

-1000000 9

Sample Output

-999,991

Calculates the value of the a+b, separating each 3 digits of the result with a comma.
