(0)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   sort(l) -> st(0, l)
   st(n, l) -> cond1(member(n, l), n, l)
   cond1(true, n, l) -> cons(n, st(s(n), l))
   cond1(false, n, l) -> cond2(gt(n, max(l)), n, l)
   cond2(true, n, l) -> nil
   cond2(false, n, l) -> st(s(n), l)
   member(n, nil) -> false
   member(n, cons(m, l)) -> or(equal(n, m), member(n, l))
   or(x, true) -> true
   or(x, false) -> x
   equal(0, 0) -> true
   equal(s(x), 0) -> false
   equal(0, s(y)) -> false
   equal(s(x), s(y)) -> equal(x, y)
   gt(0, v) -> false
   gt(s(u), 0) -> true
   gt(s(u), s(v)) -> gt(u, v)
   max(nil) -> 0
   max(cons(u, l)) -> if(gt(u, max(l)), u, max(l))
   if(true, u, v) -> u
   if(false, u, v) -> v

Q is empty.

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

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