A language with N digits in it is using a Base N number system. Some 'languages' you are used to are decimal (0123456789), hexadecimal (0123456789abcdef) and binary (01)
The language oF8 is essentially a Base 3 language. Think of of8 as being 012. Therefore, the number Fo8 in this language is actually like the base 3 number 102 which is 2 + (0*3^1) + (1*3^2) = 11 decimal. The number 11 decimal in the language ABCD would be 11 decimal = 31 base 4 = DB. So, if the question was Fo8 oF8 ABCD then the answer would be DB. Alternatively, the input 16 0123456789 0123456789ABCDEF is merely saying to convert the decimal number 16 into hexadecimal. Hope that helps!
