Large Number Multiplication

Background:

Multiplying integers is easy, provided they fit within 32 bits. Unfortunately, not everything falls within 32 bits. We want exact results for multiplying two obnoxiously large numbers.

Input:

Each input set consists of two lines. Each line consists of a positive integer no more than 100 digits in length. There are no spaces on a line.

Output:

For each input set, output the result of multiplying the two integers togther. All leading zeros should be repressed.

Sample Input:

9
