We consider the following Problem:
Strict Trs:
{ plus(x, y) -> plusIter(x, y, 0())
, plusIter(x, y, z) -> ifPlus(le(x, z), x, y, z)
, ifPlus(true(), x, y, z) -> y
, ifPlus(false(), x, y, z) -> plusIter(x, s(y), s(z))
, le(s(x), 0()) -> false()
, le(0(), y) -> true()
, le(s(x), s(y)) -> le(x, y)
, sum(xs) -> sumIter(xs, 0())
, sumIter(xs, x) -> ifSum(isempty(xs), xs, x, plus(x, head(xs)))
, ifSum(true(), xs, x, y) -> x
, ifSum(false(), xs, x, y) -> sumIter(tail(xs), y)

, head(nil()) -> error()
, head(cons(x, xs)) -> x

, tail(cons(x, xs)) -> xs
, a() -> b()
