Q restricted rewrite system:
The TRS R consists of the following rules:

   app(p, app(s, x)) -> x
   app(fact, 0) -> app(s, 0)
   app(fact, app(s, x)) -> app(app(*, app(s, x)), app(fact, app(p, app(s, x))))
   app(app(*, 0), y) -> 0
   app(app(*, app(s, x)), y) -> app(app(+, app(app(*, x), y)), y)
   app(app(+, x), 0) -> x
   app(app(+, x), app(s, y)) -> app(s, app(app(+, x), y))
   app(app(map, f), nil) -> nil
   app(app(map, f), app(app(cons, x), xs)) -> app(app(cons, app(f, x)), app(app(map, f), xs))

Q is empty.

(1) Overlay + Local Confluence (EQUIVALENT)
The TRS is overlay and locally confluent. By [NOC] we can switch to innermost.
