WORST_CASE(?,O(n^1))
* Step 1: Ara WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            f(a,cons(x,k)) -> f(cons(x,a),k)
            f(a,empty()) -> g(a,empty())
            g(cons(x,k),d) -> g(k,cons(x,d))
            g(empty(),d) -> d
        - Signature:
            {f/2,g/2} / {cons/2,empty/0}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {f,g} and constructors {cons,empty}
