#P100C. A+B

A+B

Description

Bijan is new to programming. He learned recently that programmers do not code every bit of their apps from scratch.

For example they never write a code to sum two integers, because their languages have the ability to do the sum. But can they use it? Can an experienced coder who has attended more than 100 contests, sum two integers?

Bijan is not sure about this. What's your opinion?

You are given two integers a and b, one per line (1 ≤ a, b < 10500). These numbers will not have any leading zeros.

Write sum of the two integers. Do not put any leading zeros.

Input

You are given two integers a and b, one per line (1 ≤ a, b < 10500). These numbers will not have any leading zeros.

Output

Write sum of the two integers. Do not put any leading zeros.
