* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          if(false(),x,y) -> nil()
          if(true(),x,y) -> cons(x,int(s(x),y))
          int(x,y) -> if(le(x,y),x,y)
          le(0(),y) -> true()
          le(s(x),0()) -> false()
          le(s(x),s(y)) -> le(x,y)
      - Signature:
          {if/3,int/2,le/2} / {0/0,cons/2,false/0,nil/0,s/1,true/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {if,int,le} and constructors {0,cons,false,nil,s,true}
