Problem:
 t(o(x1)) -> m(a(x1))
 t(e(x1)) -> n(s(x1))
 a(l(x1)) -> a(t(x1))
 o(m(a(x1))) -> t(e(n(x1)))
 s(a(x1)) -> l(a(t(o(m(a(t(e(x1))))))))
 n(s(x1)) -> a(l(a(t(x1))))

Proof:
 String Reversal Processor:
  o(t(x1)) -> a(m(x1))
  e(t(x1)) -> s(n(x1))
  l(a(x1)) -> t(a(x1))
  a(m(o(x1))) -> n(e(t(x1)))
  a(s(x1)) -> e(t(a(m(o(t(a(l(x1))))))))
  s(n(x1)) -> t(a(l(a(x1))))
