Thank you so much for your kind advice. I've modified the translation, please take a look to check if everything is OK. Thanks!

Both inputs should be unsigned.

There shouldn't be any global using statements in tests.

Random tests should use random header's functionality.

The reference solution should not be preloaded.

The output type should be char (maybe even enum/enum class but that's too cumbersome, IMO).

5 minutes?

This kata has me wondering what the record is for shortest living kata in beta

(this is the reason for the 4th point of FArekkusu's issue. Closing here, as duplicate of the below issue)

this shouldn't be possible... ;)

• Sample also does not show the expected result and gives away the function name

PS: Happy Chinese New Year too, but you can always express it in words instead of a kata OwO XDDD

• string header is not included
• Initial solution is using string instead of std::string
• The parameter type should be const std::string &
• The reference solution shouldn't be preloaded
• No random tests
• Concatenating strings is neither novel nor interesting kata idea

I have created C++ translation but not approved yet.

Hope you would like it!
