Oh I'm sorry, I guess the C++ version is how it's ment to be.

Personally it seems the ratings now are affected by how fast or easy a person found a kata not by the reference the kata ranking guide gives you, I'll take a look at disabling the use of BigInteger like the other katas.

In C++ it's basically a double for loop, although I only joined some weeks ago, so I don't know how were the ratings back then.

what language is too easy?
also bare in mind this kata was created over a year ago and the ratings reflect that.

For some reason, you need to add "using namespace std;" to be able to run the final tests in C++ (it won't compile otherwise).

Also, I think it's too easy for 4 kyu, although I guess it can not be changed anymore.

I have the same issue.
