FastCode Challenge: Large Products

Create a program to compute the product of several large, positive integers.

Input

Each dataset is a text file containing decimal integers. Each integer is on a line by itself and may be upto 100 digits in length. The following shows a trivial example of this format.

3
7
11
2
99
10000000000000000000000000000000000000000

The decimal expansion of the product of the above numbers is "457380000000000000000000000000000000000000000".

Output

Your program should compute the MD5 hash of the decimal expansion of the product of all integers provided. For example, the above input should produce the following.

{
    "answer" : "11a2df973c8276dfab4f429908de8d1c"
}
