it seems that it was fixed

Added this to the description:

Note: a digit can belong to two adjacent digit-pairs. For example, in string 1???9??1, 1???9 is a digit-pair, 9??1 is also a digit-pair.

But there are only two question marks between 9 and 1(9??1)

You should try asking this here as CW forum is practically dead.

my fault, I modified a bit the assertion for the anti-cheat, that made it a bit too much "blind" (mmmh... unwanted pun here... x) ). Should be better, now.

I think it's safe to close the suggestion here.

Also, reported another issue myself :(

mm, right... Forgot that the first message isn't editable in that section... :/

'r', not 'w'. Yes, like good old times with arguments.callee in JS...

wtf... X/

confirmed, raising on github.

@reivhax: could you edit your message to remove the info, please?

Could you elaborate? I've just tested this and main.py is inaccesible to me.
