Problem

Write a program that reads two integers A and B and prints A+B. A and B are large enough that they do not fit in a 64-bit integer.

Input

The first line contains A and B, separated by a single space. (0<A,B<10100000 < A, B < 10^{10000})

Output

Print A+B on the first line. Do not print leading zeros.
