MAYBE

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

Strict Trs:
  { h(x, c(y, z)) -> h(c(s(y), x), z)
  , h(c(s(x), c(s(0()), y)), z) -> h(y, c(s(0()), c(x, z))) }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

The input cannot be shown compatible

Arrrr..
