Seven years later, I'll mark this as resolved.

thats why it said
minimum

Yeah, jolaf. That would be great if all translations contained a table.

For Java, there is no mention on where it is. I didn't solve part 2/3 in Java, maybe the MorseCode map is mentioned there, somewhere.

I had to come up with my own table, because neither the Description had it, nor the initial code had any reference to it (e.g. import, or anything).

Fixed

Same issue today: 'Testing for E0x9', valid? result is not None?

It is not.

Fixed.

Description updated.

Would be nice if someone could finally fix this issue.
Nice kata otherwise.

The instructions still do not say that an empty array should be accounted for.

@GiacomoSorbi

Issue resolved.

Ignoring the MIN number of group requirement,
yes, there is a math reason behind this!

No issue, you're searching for the MINIMUM number of groups (it's stated in the description!)

I am unable to reproduce it (it works fine with my test code): can you post your code?
