MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          fac(s(x)) -> *(fac(p(s(x))),s(x))
          p(s(0())) -> 0()
          p(s(s(x))) -> s(p(s(x)))
      - Signature:
          {fac/1,p/1} / {*/2,0/0,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {fac,p} and constructors {*,0,s}
