MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          facIter(x,y) -> if(isZero(x),minus(x,s(0())),y,times(y,x))
          factorial(x) -> facIter(x,s(0()))
          if(false(),x,y,z) -> facIter(x,z)
          if(true(),x,y,z) -> y
          isZero(0()) -> true()
          isZero(s(x)) -> false()
          minus(x,0()) -> x
          minus(x,s(y)) -> p(minus(x,y))
          minus(0(),x) -> 0()
          p(0()) -> 0()
          p(s(x)) -> x
          plus(0(),x) -> x
          plus(s(x),y) -> s(plus(x,y))
          times(0(),y) -> 0()
          times(s(x),y) -> plus(y,times(x,y))
      - Signature:
          {facIter/2,factorial/1,if/4,isZero/1,minus/2,p/1,plus/2,times/2} / {0/0,false/0,s/1,true/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {facIter,factorial,if,isZero,minus,p,plus
          ,times} and constructors {0,false,s,true}
