TIMEOUT

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

Strict Trs:
  { le(0(), Y) -> true()
  , le(s(X), 0()) -> false()
  , le(s(X), s(Y)) -> le(X, Y)
  , app(nil(), Y) -> Y
  , app(cons(N, L), Y) -> cons(N, app(L, Y))
  , low(N, nil()) -> nil()
  , low(N, cons(M, L)) -> iflow(le(M, N), N, cons(M, L))
  , iflow(true(), N, cons(M, L)) -> cons(M, low(N, L))
  , iflow(false(), N, cons(M, L)) -> low(N, L)
  , high(N, nil()) -> nil()
  , high(N, cons(M, L)) -> ifhigh(le(M, N), N, cons(M, L))
  , ifhigh(true(), N, cons(M, L)) -> high(N, L)
  , ifhigh(false(), N, cons(M, L)) -> cons(M, high(N, L))
  , quicksort(nil()) -> nil()
  , quicksort(cons(N, L)) ->
    app(quicksort(low(N, L)), cons(N, quicksort(high(N, L)))) }

Answer:
  TIMEOUT

Computation stopped due to timeout after 60.0 seconds.

Arrrr..
