Also, please raise this as a question instead of an issue :)

using math.log is clever, but creating a list, calling range, reversing it, and creating a tuple is excess

For n=50, I'm getting [1, 4, 9, 49] with my algorithm. The problem asks for "largest possible values". In my world, 9 is larger than 8.

I have the same problem. A lot of people are having trouble with unicode support, but this is the third test and the alphabet and key do not require unicode support.Can anyone spare a hint?

Nevermind... This kata should give the user a hint that maybe he should make copies of the objects. OR a result from a previous problem should not be inherited in the next problem.

Same problem with me. I am getting:

a = [4, 6, 8]
b = [3, 4, 5]
subtraction = [1, 2, 3]
expected = [-2, -2, -2]

This appears to be an issue.

I didn't write the Python version, I wrote the three originals.

It doesn't work on the command line for me.

Taking the example of 153, you seem to be taking cube roots. You should be raising each digit to its third power and adding it to a total like in the explanation of the Kata.

I hope that helps...
