MAYBE

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

Strict Trs:
  { half(0()) -> 0()
  , half(s(0())) -> 0()
  , half(s(s(x))) -> s(half(x))
  , lastbit(0()) -> 0()
  , lastbit(s(0())) -> s(0())
  , lastbit(s(s(x))) -> lastbit(x)
  , conv(0()) -> cons(nil(), 0())
  , conv(s(x)) -> cons(conv(half(s(x))), lastbit(s(x))) }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

The input cannot be shown compatible

Arrrr..
