I imagined a golf Challenge which seemed pretty interesting to me. But to make it doable, I'd like to offer one or several functions to challengers.
- Function 1
Input: Integer a; id of a country
Output: the total population of the country 'a'
- Function 2
Input: Integer a, Integer b
Output: the distance in kilometers between country 'a' and country 'b'
Is it possible to make it fair for everyone in this case?
