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

   le(s(x), 0) -> false
   le(0, y) -> true
   le(s(x), s(y)) -> le(x, y)
   double(0) -> 0
   double(s(x)) -> s(s(double(x)))
   log(0) -> logError
   log(s(x)) -> loop(s(x), s(0), 0)
   loop(x, s(y), z) -> if(le(x, s(y)), x, s(y), z)
   if(true, x, y, z) -> z
   if(false, x, y, z) -> loop(x, double(y), s(z))
   maplog(xs) -> mapIter(xs, nil)
   mapIter(xs, ys) -> ifmap(isempty(xs), xs, ys)
   ifmap(true, xs, ys) -> ys
   ifmap(false, xs, ys) -> mapIter(droplast(xs), cons(log(last(xs)), ys))
   isempty(nil) -> true
   isempty(cons(x, xs)) -> false
   last(nil) -> error
   last(cons(x, nil)) -> x
   last(cons(x, cons(y, xs))) -> last(cons(y, xs))
