Hi are you accepting translations? If so I might do a Go one.

There's always one.

So I'm guessing this is a kata that is more about finding a formula to calculate this right? Rather than a coding kata?

Awesome kata, thanks very much. I enjoyed solving it.

Nice kata, thanks.

See above, Go tests seem to have a problem. I have tested some of them with my Python code and I get the same results as my Go code.

For instance:
Encode Key: OZzhEOAUlkOZDh Alpha: ckclVDAJzUsohOEJZQVDw Text: kZOlaAosDQbUE10FcO

My answer: EocJaDQDzVbVD10FzV Expected answer: EocJaDQDkVbVh10FsV

Haha, I just came here to say something is wrong with the Go tests.

Awesome kata, thanks.

Nice kata, I learned a bit about Python ojbects.

Really nice kata, thanks, I had fun solving it :)

It says what it is. With a link. What more do you want?

Yes you're right. I just get this error when I print the larger int values. I guess the ints get converted to strings first, and there's a limit on string lengths.

"ValueError: Exceeds the limit (4300) for integer string conversion; use sys.set_int_max_str_digits() to increase the limit"

See above, this occurs when you print the integer value.

In particular I don't think you can solve the problem without a call to this: sys.set_int_max_str_digits()

Did you ban sys? It's needed for large ints in Python.
