I'll fork the translation for merge conflicts when the C++ situation has been cleaned up.

The reference solution should be inside a Describe block in C++.

The description became wrong after the C++ translation was approved.

As mentioned below, a translation approval forked up the description.

Yes, it should be fixed, no, we don't need multiple reminders of that.

It should be mentioned that in Java tests expect null instead of -1.
Tests or description should be fixed

thanks for suggestion
