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

   app(x, y) -> helpa(0, plus(length(x), length(y)), x, y)
   plus(x, 0) -> x
   plus(x, s(y)) -> s(plus(x, y))
   length(nil) -> 0
   length(cons(x, y)) -> s(length(y))
   helpa(c, l, ys, zs) -> if(ge(c, l), c, l, ys, zs)
   ge(x, 0) -> true
   ge(0, s(x)) -> false
   ge(s(x), s(y)) -> ge(x, y)
   if(true, c, l, ys, zs) -> nil
   if(false, c, l, ys, zs) -> helpb(c, l, greater(ys, zs), smaller(ys, zs))
   greater(ys, zs) -> helpc(ge(length(ys), length(zs)), ys, zs)
   smaller(ys, zs) -> helpc(ge(length(ys), length(zs)), zs, ys)
   helpc(true, ys, zs) -> ys
   helpc(false, ys, zs) -> zs
   helpb(c, l, cons(y, ys), zs) -> cons(y, helpa(s(c), l, ys, zs))

Q is empty.

----------------------------------------

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