Today's challenge: given a number of digits, print the sum of all numbers that can be expressed using all such digits.

That's simple enough, right? So, give us the sum for the input 54321.

Here's a quick example: for the digits 1 and 2, the two numbers that can be expressed are 12 and 21, which gives us a sum of 33.

The answer

As usual, the answer has been base64 encoded by Austrian craftsmen working in a small village in the foothills of the Alps. Enjoy!
