The TRS R consists of the following rules: lessElements(l, t) -> lessE(l, t, 0) lessE(l, t, n) -> if(le(length(l), n), le(length(toList(t)), n), l, t, n) if(true, b, l, t, n) -> l if(false, true, l, t, n) -> t if(false, false, l, t, n) -> lessE(l, t, s(n)) length(nil) -> 0 length(cons(n, l)) -> s(length(l)) toList(leaf) -> nil toList(node(t1, n, t2)) -> append(toList(t1), cons(n, toList(t2))) append(nil, l2) -> l2 append(cons(n, l1), l2) -> cons(n, append(l1, l2)) le(s(n), 0) -> false le(0, m) -> true le(s(n), s(m)) -> le(n, m) a -> c a -> d S is empty.
