Base 9 Calculator

Background:

Normally, you use base 10 to do arithmetic. In computer science, you also deal with binary (base 2), octal (base 8), and hex (base 16). In this problem, we'll worry about base 9, which uses the digits 0..8.

Input:

each line of input will contain two numbers separated by a space. Each number is in base 9. If converted to base 10, the numbers would be greater than 0, and smaller than 65000.

Output:

For each input, your program should add the two numbers together and print the result (in base 9).

Sample Input:

148 765
111 888
8734 8345

Sample Output:

1024
1110
18180
