* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          id(0()) -> 0()
          id(s(x)) -> s(id(x))
          if2(false(),b2,x,y) -> if3(b2,x,y)
          if2(true(),b2,x,y) -> 0()
          if3(false(),x,y) -> x
          if3(true(),x,y) -> mod(minus(x,y),s(y))
          if_mod(false(),b1,b2,x,y) -> if2(b1,b2,x,y)
          if_mod(true(),b1,b2,x,y) -> 0()
          le(0(),y) -> true()
          le(s(x),0()) -> false()
          le(s(x),s(y)) -> le(x,y)
          minus(x,0()) -> x
          minus(s(x),s(y)) -> minus(x,y)
          mod(x,y) -> if_mod(zero(x),zero(y),le(y,x),id(x),id(y))
          zero(0()) -> true()
          zero(s(x)) -> false()
      - Signature:
          {id/1,if2/4,if3/3,if_mod/5,le/2,minus/2,mod/2,zero/1} / {0/0,false/0,s/1,true/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {id,if2,if3,if_mod,le,minus,mod,zero} and constructors {0
          ,false,s,true}
