MAYBE

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

Strict Trs:
  { pairNs() -> cons(0(), incr(oddNs()))
  , incr(cons(X, XS)) -> cons(s(X), incr(XS))
  , oddNs() -> incr(pairNs())
  , take(0(), XS) -> nil()
  , take(s(N), cons(X, XS)) -> cons(X, take(N, XS))
  , zip(X, nil()) -> nil()
  , zip(cons(X, XS), cons(Y, YS)) -> cons(pair(X, Y), zip(XS, YS))
  , zip(nil(), XS) -> nil()
  , tail(cons(X, XS)) -> XS
  , repItems(cons(X, XS)) -> cons(X, cons(X, repItems(XS)))
  , repItems(nil()) -> nil() }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

The input cannot be shown compatible

Arrrr..
