99-problems

Maybe someone who knows more about logic programming can correct me, but it seems that these are just imperative solutions to problems designed to be solved in a logical programming context. For example, take a look at problem 2.07 from the original 99-problems for [Prolog][1] and compare it to the [Java][2] solution in the linked repo. In Prolog, you're defining relations, so with GCD defined, you can compute the GCD (g) given two integers a and b, but you can also compute possible values for b, given a and g, for example. The Java solution doesn't allow for anything like that. So, given the README information, I expected to see the implementations in different language platforms utilize some prolog-esque logic programming library (like core.logic for Clojure), but that isn't the case.
