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!
