WORST_CASE(?,O(n^1))
* Step 1: Ara WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            2nd(cons(X,XS)) -> head(activate(XS))
            activate(X) -> X
            activate(n__from(X)) -> from(X)
            activate(n__take(X1,X2)) -> take(X1,X2)
            from(X) -> cons(X,n__from(s(X)))
            from(X) -> n__from(X)
            head(cons(X,XS)) -> X
            sel(0(),cons(X,XS)) -> X
            sel(s(N),cons(X,XS)) -> sel(N,activate(XS))
            take(X1,X2) -> n__take(X1,X2)
            take(0(),XS) -> nil()
            take(s(N),cons(X,XS)) -> cons(X,n__take(N,activate(XS)))
        - Signature:
            {2nd/1,activate/1,from/1,head/1,sel/2,take/2} / {0/0,cons/2,n__from/1,n__take/2,nil/0,s/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {2nd,activate,from,head,sel,take} and constructors {0,cons
            ,n__from,n__take,nil,s}
