Problem

Write a program that reads two integers A and B and prints A+B. The two values can be far too large for a 64-bit integer type.

Input

The first line contains A and B, separated by a single space. (0<A,B<101000000 < A, B < 10^{100000})

Both values are given in decimal with no leading zeros.

Output

Print A+B on the first line, with no leading zeros.
