MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          app(l,nil()) -> l
          app(cons(x,l),k) -> cons(x,app(l,k))
          app(nil(),k) -> k
          plus(0(),y) -> y
          plus(s(x),y) -> s(plus(x,y))
          sum(app(l,cons(x,cons(y,k)))) -> sum(app(l,sum(cons(x,cons(y,k)))))
          sum(cons(x,cons(y,l))) -> sum(cons(plus(x,y),l))
          sum(cons(x,nil())) -> cons(x,nil())
      - Signature:
          {app/2,plus/2,sum/1} / {0/0,cons/2,nil/0,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {app,plus,sum} and constructors {0,cons,nil,s}
