Can you explain for me, because comment after which you understand is hidden

Not an issue now!

Reraised above with more detail

Fixed

Approved

English is not my native language, too ;-)

A=2 B=4
divisors=[2,3]
for each divisor in divisors([2,3]):
  2 is a divisor of AB, both 2 and 4
  3 is not a divisor of AB, neither 2 nor 4

as english is not my native language could you explain what does it mean "(each integer from the array divisors) is either (a divisor of both A and B) or (neither A nor B)"
first part is easy, if each element in array is a divisor of A and B, but i don't understand what does it mean " each element in array is neither a divisor A nor B"

Zzz..
Goodnight.
I'm flying to my bed, now. ;-)

but the definition of friends was written in description clearly..

Please look at my comment bellow. ;-)

The C++ translation still expects a different behavious than the other language versions. See the issue above.

Currently the vector argument is called 'array' in C++ translation.

That confused me for a while :)

Random tests expect the following:
123456789101112...
23456789101112...
...
1011121314151617181920...
011121314151617181920...
11121314151617181920...

Could you fix the C++ solution? Please read the issue!
