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

   minus(0, y) -> 0
   minus(x, 0) -> x
   minus(s(x), s(y)) -> minus(x, y)
   plus(0, y) -> y
   plus(s(x), y) -> plus(x, s(y))
   zero(s(x)) -> false
   zero(0) -> true
   p(s(x)) -> x
   div(x, y) -> quot(x, y, 0)
   quot(x, y, z) -> if(zero(x), x, y, plus(z, s(0)))
   if(true, x, y, z) -> p(z)
   if(false, x, s(y), z) -> quot(minus(x, s(y)), s(y), z)

Q is empty.

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

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

(2)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   minus(0, y) -> 0
   minus(x, 0) -> x
   minus(s(x), s(y)) -> minus(x, y)
   plus(0, y) -> y
   plus(s(x), y) -> plus(x, s(y))
   zero(s(x)) -> false
   zero(0) -> true
   p(s(x)) -> x
   div(x, y) -> quot(x, y, 0)
   quot(x, y, z) -> if(zero(x), x, y, plus(z, s(0)))
   if(true, x, y, z) -> p(z)
   if(false, x, s(y), z) -> quot(minus(x, s(y)), s(y), z)

The set Q consists of the following terms:

   minus(0, x0)
   minus(x0, 0)
   minus(s(x0), s(x1))
   plus(0, x0)
   plus(s(x0), x1)
