@temen no it's not.
"The goal of this Kata is to reduce the passed integer to a single digit --->>> (if not already) <<<---"

No 0s allowed

I think the anticheat has been removed fully. I'll raise an issue.

The language of the instructions uses:
"You need to" ... "by gradually pulling apart"
and
"You should repeat the following steps" ...

Yet also says:
"The Kata title gives a hint of one technique to solve."
implying you may solve it other ways.

If a kata demands the use of a specific technique then it should fail those that do not meet that requirement.
But this is not the case.

done. thanks.
