* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          check(0()) -> zero()
          check(s(0())) -> odd()
          check(s(s(0()))) -> even()
          check(s(s(s(x)))) -> check(s(x))
          half(0()) -> 0()
          half(s(0())) -> 0()
          half(s(s(x))) -> s(half(x))
          if(even(),x,y,z,u) -> plus(timesIter(half(x),y,half(z)),timesIter(half(x),y,half(s(z))))
          if(odd(),x,y,z,u) -> timesIter(p(x),y,u)
          if(zero(),x,y,z,u) -> z
          p(0()) -> 0()
          p(s(x)) -> x
          plus(0(),y) -> y
          plus(s(x),y) -> s(plus(x,y))
          times(x,y) -> timesIter(x,y,0())
          timesIter(x,y,z) -> if(check(x),x,y,z,plus(z,y))
      - Signature:
          {check/1,half/1,if/5,p/1,plus/2,times/2,timesIter/3} / {0/0,even/0,odd/0,s/1,zero/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {check,half,if,p,plus,times,timesIter} and constructors {0
          ,even,odd,s,zero}
