WORST_CASE(?,O(n^1))
* Step 1: Ara WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            fold#3(Cons(x4,x2)) -> plus#2(x4,fold#3(x2))
            fold#3(Nil()) -> 0()
            main(x1) -> fold#3(x1)
            plus#2(0(),x12) -> x12
            plus#2(S(x4),x2) -> S(plus#2(x4,x2))
        - Signature:
            {fold#3/1,main/1,plus#2/2} / {0/0,Cons/2,Nil/0,S/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {fold#3,main,plus#2} and constructors {0,Cons,Nil,S}
