MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          if_mod(false(),false(),x,y,z) -> x
          if_mod(false(),true(),x,y,z) -> mod(z,y)
          if_mod(true(),b,x,y,z) -> divByZeroError()
          isZero(0()) -> true()
          isZero(s(x)) -> false()
          le(0(),y) -> true()
          le(s(x),0()) -> false()
          le(s(x),s(y)) -> le(x,y)
          minus(x,x) -> 0()
          minus(x,0()) -> x
          minus(0(),x) -> 0()
          minus(s(x),s(y)) -> minus(x,y)
          mod(x,y) -> if_mod(isZero(y),le(y,x),x,y,minus(x,y))
      - Signature:
          {if_mod/5,isZero/1,le/2,minus/2,mod/2} / {0/0,divByZeroError/0,false/0,s/1,true/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {if_mod,isZero,le,minus,mod} and constructors {0
          ,divByZeroError,false,s,true}

      The input can not be schown compatible.
