Title 1198:a+b (large number added)

Title Description:

Implement an adder so that it can output the value of a+b.

Input:

The input includes two numbers A and b, where A and B are not more than 1000 bits in number.

Output:

There may be multiple sets of test data, for each set of data,
The value of the output a+b.

Sample input:

2 610000000000000000000 10000000000000000000000000000000

Sample output:

810000000000010000000000000000000
