so cheesy

Fixed :)

This is known compatibility issue with the new runner we launched recently. https://github.com/Codewars/codewars.com/wiki/List-of-Affected-Kata

I'll see if I can fix this soon.

Traceback (most recent call last):
  File "main.py", line 15, in <module>
    strexp = __randexp__(Nfact)
NameError: name '__randexp__' is not defined

Fails on the last test with this message.

Do you know how to efficiently test 2D array with C++ Unit test Assert::That? If you know please tell me because I didn't find (maybe I was too lazy:-).

Why use strings in C++? It doesn't make sense. Guess, author was just lazy.
