* Step 1: Ara WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            comp_f_g#1(comp_f_g(x7,x9),walk_xs_3(x8),x12) -> comp_f_g#1(x7,x9,Cons(x8,x12))
            comp_f_g#1(walk_xs(),walk_xs_3(x8),x12) -> Cons(x8,x12)
            main(Cons(x4,x5)) -> comp_f_g#1(walk#1(x5),walk_xs_3(x4),Nil())
            main(Nil()) -> Nil()
            walk#1(Cons(x4,x3)) -> comp_f_g(walk#1(x3),walk_xs_3(x4))
            walk#1(Nil()) -> walk_xs()
        - Signature:
            {comp_f_g#1/3,main/1,walk#1/1} / {Cons/2,Nil/0,comp_f_g/2,walk_xs/0,walk_xs_3/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {comp_f_g#1,main,walk#1} and constructors {Cons,Nil
            ,comp_f_g,walk_xs,walk_xs_3}
