Two-fer or 2-fer is short for two for one. One for you and one for me.
Given a name, return a string with the message:
One for X, one for me.
Where X is the given name.
However, if the name is missing, return the string:
One for you, one for me.
Here are some examples:
| Name | String to return |
|---|---|
| Alice | One for Alice, one for me. |
| Bob | One for Bob, one for me. |
| One for you, one for me. | |
| Zaphod | One for Zaphod, one for me. |
