This problem is ask you plus two big nubmer, please help him, when you solve thisproblem you can

speak to Three-God,"Oh, Please give me a diffculte one, this oneis too easy".

Input

There are muti-case
For each case, there are two integers, n, m (0 < n, m < 10^10000).

Output

Calculate two integers' sum

Sample Input

1 1
2 3
10000 100000

Sample Output

2
5
110000

题解：这设么破oj,竟然需要前导0，我曹，第一次见，WR了几十次……

输入时候有前导0，输出时必须也有……
