MAYBE

We are left with following problem, upon which TcT provides the
certificate MAYBE.

Strict Trs:
  { intlist(nil()) -> nil()
  , intlist(cons(x, y)) -> cons(s(x), intlist(y))
  , int(s(x), s(y)) -> intlist(int(x, y))
  , int(s(x), 0()) -> nil()
  , int(0(), s(y)) -> cons(0(), int(s(0()), s(y)))
  , int(0(), 0()) -> cons(0(), nil()) }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

The input cannot be shown compatible

Arrrr..
