The greater value of 1 and 2 = 2
The greater value of 2 and 1 = 2
The greater value of 'a' and 'z' = z
The greater value of 3.14 and 2.72 = 3.14

Does the max function work with strings? Yes.
Strings can be compared alphabetically, so max() works with string data types.
Example: zebra is greater alphabetically.
